feat(platform/azure): Allow to bypass certain policies for auto-merge

[janicmikes]

Changes

This allows to use bypass functionality of Azure DevOps to provide a seamless auto-merge even if some policies are not met.

Policies one might want to bypass:

• Require at least n reviewers (might also exclude the user of the last push)
• Require specific reviewers (code owners)
• Require work items to be linked (related to the config azureWorkItemId)
• Require builds to pass (bound to the ignoreTests config)
• Any other custom defined policies (UUID required)

Context

Automatic Merges for Azure DevOps might not be done (using merge) if some policies prevent the pr from being merged.
This can be bypassed by using the bypass policy option when completing the pull-request.

The thing is, that any other policy, not to be bypassed will prevent the bypass from being used.
