Merge branch 'stable-2.14'

* stable-2.14:
  Remove redundant type definition
  Fix documentation
  Fix broken default configuration
  Remove buck build
  Stand-alone bazel build for events-log plugin
  Attach sources of byte-buddy and objenesis in eclipse
  Fix in-tree Eclipse project generation
  Remove dependency already packaged in gerrit-plugin-api
  Use double quotes in external_plugin_deps.bzl
  Format build file with buildifier

Test plan:

- bazel clean --expunge
- bazel build events-log
- bazel test --nocache_test_results //...
- Deploy plugin to gerrit master site
- Verify plugin loads without errors
- Do some change operations: create change, review, rebase, etc...
- Query REST endpoint
- Verify events for above operations are present

Just checking that a plugin builds is not enough to vote Verified
