Auto match version to branch on deployment and have it part of the report generated for the optional reporting system

[naorlivne]

Expected/Wanted Behaviour

The version of the worker should be auto set to match the branches.

the $TRAVIS_BRANCH envvar will likely be part of the solution but as this should be a change in the codebase itself (rather then just assigning the variable value a more complex solution the just os.getenv(TRAVIS_BRANCH) will be needed.

after there is a version as part of the codebase it should be added to be part of the reports that are sent to the optional reporting system.

Possible solutions include:

• https://pypi.org/project/bump2version/
• https://pypi.org/project/changes/
• https://pypi.org/project/zest.releaser/

Actual Behaviour

Version is manually set before deployments.
