Support AWS CodeCommit Remote

[jameshueston]

Description

Please make a default integration for AWS CodeCommit, or enable a Custom Integration to work. Our git repo url is:
url = ssh://git-codecommit.us-east-1.amazonaws.com/v1/repos/Something

Your variables render to the following:

${repoBase} "v1"
${repo}     "v1/repos/Something"
${repoPath} "repos/Something"

If you could allow string manipulation functions like Split(), or the equivalent, that would work.

Thanks in advance for either a workaround or adoption, and thanks very much for a great plugin and service!
