TB2: respect custom configuration options provided during gerrit-buildbot build scheduling
Ci-infra bugs are now tracked in redmine. Copied from bugzilla bug #71033
TB2 script currently hard coded the configuration optons in the profile. It would be advantageous to be able to provide aditional configuration options. Gerrt-buildbot plugin was extended to expose this functionality through UI (Schedule button) and SSH `buildbot-schedule` command. The configuration option can be specified and returned to the engaged Tinderxbox with SSH `buildbot-get`command .
The only missing part is on tinderbox side to pick up the configuration options and pass them to the build. To be more accurate, new BASH variable is get sourced as outcome of `buildbot get` command: GERRIT_TASK_OPTIONS.
The enhanced version of gerrit-buildbot plugin is deployed on the staging gerrit test installation and can be used for tests .
Note: all enhancements to gerrit-buildbot plugin were done on top of vanilla Gerrit 2.8.
