Bitbucket groups are not supported in Pipeline deployment

Bitbucket groups are not supported in Pipeline deployment.

Currently there is an option 'Only admin can deploy' which allows only Admin to perform deployment which is not a good enough granular control.

There should be provision to specify Bitbucket groups who can perform deployment into specific environments.

For example -

• Deployment in Development environment can happen by someone in group 'dev', 
• Deployment in UAT environment can happen by someone in group 'qa'
• Deployment in Prod environment can happen by someone in group 'devops'
