AWS CodeCommit support

[tony]

AWS CodeCommit (HomePage, docs):

Via (page):

For example, to clone a repository named MyDemoRepo to a local repo named my-demo-repo:

git clone codecommit://MyDemoRepo my-demo-repo

To clone the same repository using a profile named CodeCommitProfile:

git clone codecommit://`CodeCommitProfile`@MyDemoRepo my-demo-repo

To clone a repository in a different AWS Region than the one configured in your profile, include the AWS Region name. For example:

git clone codecommit::ap-northeast-1://MyDemoRepo my-demo-repo
