How Sentry discovers plugins

You can use the pkg_resources library to query against sentry.plugins. Each plugin has an .egg directory that defines an entry_point.txt file.

>> import pkg_resources
>> list(pkg_resources.iter_entry_points('sentry.plugins'))
EntryPoint.parse('sentry_statsd = sentry_statsd.plugin:StasdPlugin'), EntryPoint.parse('hipchat = sentry_hipchat.models:HipchatMessage')]
