The default naming convention for patch branches created in
the GitHub UI when editing files is: {username}-patch-{number}
The default naming convention for revert branches created in
the GitHub UI when reverting a PR is: revert-{pr_number}-{pr_branch_name}
This exclusion will prevent Shippable from running on these
branches until a PR is created.
This will disable the integration tests for all network platforms &
modules, though the unit tests will still run.
This is needed while a large refactor of the networking code is done.
