feat(ci-bot): add a patch counter script

Add a simple script to count the number of patches in each project on
tforg from a given query. By default this will be the patches in review,
although this is configurable from an argument.

The implementation is very similar to the ci_status_bot so that they can
be used together from a script as well as standalone if necessary.
