Allow for multiple master forks

[sladg]

As a developer with monorepo, I want to control what application get's deployed where while keeping the code together.
To do this in Bitbucket, I need to have separate branches with it's own deployment steps.
To do this, release utils needs to support forking master to multiple release branches.

Expected behaviour:

• I pass website and api as parameters to release command,
• release command forks master to release/website-v0.0.0 and release/api-v0.0.0.
