[Enterprise Search] Set up basic scaffolding for Cypress tests in Kibana (#108309)

* Set up tsconfigs

- Required if we're going to have several different Cypress suites (one for each plugin/product essentially) in order for global cy.() commands and it()/describe() to register as expected

@see https://docs.cypress.io/guides/tooling/typescript-support#Clashing-types-with-Jest

* Set up shared commands and routes

NOTE: Unlike ent-search, shared/ will *not* have its own set of tests - rather, shared/cypress is a resource/set of helpers for other test suites to extend/import/etc.

* Create basic Enterprise Search Overview E2E tests

- For happy path testing, we _likely_ shouldn't need more than these tests going forward

- If we ever want to add an error connecting test however, this is likely where it should go (or alternatively, use Kibana's FTR with Enterprise Search host set but not spun up)

* Set up App Search Cypress test scaffolding

- placeholder/hello world test only

* Set up Workplace Search Cypress test scaffolding

- placeholder/hello world test only

* Add helper script and update README

* Add config setup & documentation for potentially running Cypress against Kibana functional server

* PR feedback: Remove unnecessary return true

 ### E2E tests
 
+We currently have two testing libraries in which we run E2E tests:
+
+- [Cypress](#cypress-tests)
+  - Will contain the majority of our happy path E2E testing
+- [Kibana's Functional Test Runner (FTR)](#kibana-ftr-tests)
+  - Contains basic tests that only run when the Enterprise Search host is not configured
+  - It's likely we will not continue to expand these tests, and might even trim some over time (to be replaced by Cypress)
+
+#### Cypress tests
+
+Documentation: https://docs.cypress.io/
+
+Cypress tests can be run directly from the `x-pack/plugins/enterprise_search` folder. You can use our handy cypress.sh script to run specific product test suites:
+
+```bash
+# Basic syntax
+sh cypress.sh {run|open} {suite}
+
+# Examples
+sh cypress.sh run overview   # run Enterprise Search overview tests
+sh cypress.sh open overview  # open Enterprise Search overview tests
+
+sh cypress.sh run as         # run App Search tests
+sh cypress.sh open as        # open App Search tests
+
+sh cypress.sh run ws         # run Workplace Search tests
+sh cypress.sh open ws        # open Workplace Search tests
+
+# Overriding env variables
+sh cypress.sh open as --env username=enterprise_search password=123
+
+# Overriding config settings, e.g. changing the base URL to a dev path, or enabling video recording
+sh cypress.sh open as --config baseUrl=http://localhost:5601/xyz video=true
+
+# Only run a single specific test file
+sh cypress.sh run ws --spec '**/example.spec.ts'
+
+# Opt to run Chrome headlessly
+sh cypress.sh run ws --headless
+```
+
+There are 3 ways you can spin up the required environments to run our Cypress tests:
+
+1. Running Cypress against local dev environments:
+   - Elasticsearch:
+     - Start a local instance, or use Kibana's `yarn es snapshot` command (with all configurations/versions required to run Enterprise Search locally)
+     - NOTE: We generally recommend a fresh instance (or blowing away your `data/` folder) to reduce false negatives due to custom user data
+   - Kibana:
+     - You **must** have `csp.strict: false` and `csp.warnLegacyBrowsers: false` set in your `kibana.dev.yml`.
+     - You should either start Kibana with `yarn start --no-base-path` or pass `--config baseUrl=http://localhost:5601/xyz` into your Cypress command.
+   - Enterprise Search:
+     - Nothing extra is required to run Cypress tests, only what is already needed to run Kibana/Enterprise Search locally.
+2. Running Cypress against Kibana's functional test server:
+   - :information_source: While we won't use the runner, we can still make use of Kibana's functional test server to help us spin up Elasticsearch and Kibana instances.
+     - NOTE: We recommend stopping any other local dev processes, to reduce issues with memory/performance
+   - From the `x-pack/` project folder, run `node scripts/functional_tests_server --config test/functional_enterprise_search/cypress.config.ts`
+   - Kibana:
+     - You will need to pass `--config baseUrl=http://localhost:5620` into your Cypress command.
+   - Enterprise Search:
+     - :warning: TODO: We _currently_ do not have a way of spinning up Enterprise Search from Kibana's FTR - for now, you can use local Enterprise Search (pointed at the FTR's `http://localhost:9220` Elasticsearch host instance)
+3. Running Cypress against Enterprise Search dockerized stack scripts
+   - :warning: This is for Enterprise Search devs only, as this requires access to our closed source Enterprise Search repo
+   - `stack_scripts/start-with-es-native-auth.sh --with-kibana`
+   - Note that the tradeoff of an easier one-command start experience is you will not be able to run Cypress tests against any local changes.
+
+##### Debugging
+
+Cypress can either run silently in a headless browser in the command line (`run` or `--headless` mode), which is the default mode used by CI, or opened interactively in an included app and the Chrome browser (`open` or `--headed --no-exit` mode).
+
+For debugging failures locally, we generally recommend using open mode, which allows you to run a single specific test suite, and makes browser dev tools available to you so you can pause and inspect DOM as needed.
+
+> :warning: Although this is more extra caution than a hard-and-fast rule, we generally recommend taking a break and not clicking or continuing to use the app while tests are running. This can eliminate or lower the possibility of hard-to-reproduce/intermittently flaky behavior and timeouts due to user interference.
+
+##### Artifacts
+
+All failed tests will output a screenshot to the `x-pack/plugins/enterprise_search/target/cypress/screenshots` folder. We strongly recommend starting there for debugging failed tests to inspect error messages and UI state at point of failure.
+
+To track what Cypress is doing while running tests, you can pass in `--config video=true` which will output screencaptures to a `videos/` folder for all tests (both successful and failing). This can potentially provide more context leading up to the failure point, if a static screenshot isn't providing enough information.
+
+> :information_source: We have videos turned off in our config to reduce test runtime, especially on CI, but suggest re-enabling it for any deep debugging.
