* tests: make integration split quantity configurable
Refactors shared splitter bash function to take a list of files on stdin
and split into a configurable number of partitions, emitting only those from
the currently-selected partition to stdout.
Also refactors the only caller in the integration_tests launcher script to
accept an optional partition_count parameter (defaulting to `2` for backward-
compatibility), to provide the list of specs to the function's stdin, and to
output relevant information about the quantity of partition splits and which
was selected.
* ci: run integration tests in 3 parts
(cherry picked from commit 3e0f488df2)

A new class of build node has recently been added which appears to have fewer
memory resources than previous nodes, causing integration test failures. The
gradle task for integration tests doesn't appear to require 4gb, so this commit
reduces the -Xmx setting to 4gb
This commit includes:
* A base Dockerfile and script to push to a Docker repo
* A per-build Dockerfile (derived from the base)
* Updates to the test scripts to allow for more parallel builds
* Docker wrappers for the tests scripts
* Update for the integration test readme to manually run the tests
* Clean up the output of the Java tests
* Remove offline tag for tests (no longer needed that we don't use docker dependent services)
This commit does NOT include:
* Changes needed for the CI system to use Docker
Fixes#8223
