This provides the central location for what must be modified when
setting up the project for a new branch or when a branch changes category
(e.g. moves from a standard release channel to the long-term support

* is_master - Whether this branch is main/master/trunk.
* is_lts_branch - Whether this branch is in the LTS channel.
* ref - The git ref containing the code for this branch.
* cq_ref_regexp - A regular expression determining the git refs that the
CQ group for this project should watch.
* try_trigger_projects - A list of names of other LUCI projects whose CQ
is allowed to trigger this project's try builders. None can also be
passed to prohibit other projects' CQ from triggering this project's try
builders.
* tree_status_host - The host of the tree status app associated with this
project. Builders with tree closers configured will notify this host and
CQ attempts will block if the host indicates the tree is closed. It also
appears at the top of the console header. None indicates there is no
associated tree status app for the project.
