'Quarantine' tests help test driven development.

Currently it is reactive and not ideal - eg to quarantine each test it must first fail and then you can quarantine it.

To aid in test driven development, we will add a command '#QuarantineNewFailingTests'
which can be put in a commit message. If Bamboo detects this in the commit message that triggered a build, it will automatically quarantine all new tests that fail.

Other features may be added after dogfooding/release depending on feedback
