Update bug LP mapping for all infra projects.

* jeepyb/cmd/update_bug.py: Update the gerrit to Launchpad project
name mapping for all projects in the openstack-infra org to
correspond to openstack-ci bugs, except those which have their own
separate LP projects already. Also alphabetize the list for easier
maintenance.
