Fix gem installer tests to enable unpinning the version of bundler
This commit removes changes the gem installer to use real gems, rather than
use `allow_instance_of` during testing, which appears to be problematic with the
latest version of bundler
This is a big chang, it:
1. Moves API specs out of their special hierarchy
2. Removes the API spec spec_helper
3. Reactivates that stats command spec (that was accidentally not being
run before due to it not having _spec as a suffix
This was required to fix the preceeding commit, where we added a
before(:each) hook to the spec_helper that wasn't being picked up in
some cases due to the existence of two spec helpers and a $LOAD_PATH
that could change.
Fixes#7132
A pack in this context is a *bundle* of plugins that can be distributed outside of rubygems; it is similar to what ES and kibana are doing, and
the user interface is modeled after them. See https://www.elastic.co/downloads/x-pack
**Do not mix it with the `bin/logstash-plugin pack/unpack` command.**
- it contains one or more plugins that need to be installed
- it is self-contains with the gems and the needed jars
- it is distributed as a zip file
- the file structure needs to follow some rules.
- As a reserved name name on elastic.co download http server
- `bin/plugin install logstash-mypack` will check on the download server if a pack for the current specific logstash version exist and it will be downloaded, if it doesn't exist we fallback on rubygems.
- The file on the server will follow this convention `logstash-mypack-{LOGSTASH_VERSION}.zip`
- As a fully qualified url
- `bin/plugin install http://test.abc/logstash-mypack.zip`, if it exists it will be downloaded and installed if it does not we raise an error.
- As a local file
- `bin/plugin install file:///tmp/logstash-mypack.zip`, if it exists it will be installed
Fixes#6168
Plugins have moved to https://github.com/logstash-plugins/... into
individual repositories. One plugin per repo.
* Add plugin install task and add required plugins for testing
* Adding a plugin task to install plugins
* Added required plugins to a prep task for the test part.
