Here we just clean up obvious errors like nonexistent lifecycles,
statuses, etc. This is initially to sync __maps__ when statuses are
deleted from lifecycles.

This is initially to fix broken lifecycle links because the URL with
Name=... doesn't retain the trailing space.

When admins update configs from web UI, the default values of inputs fully
contain current config values, so there is no need to merge old values after
update. By not merging old values, admins now are able to delete keys from
hash configs.

This is initially to support lifecycle deletions.

This gives admins hints of the issue of %Lifecycles configuration.

This is initially to get rid of server errors for our tests that contain
other unsupported types(e.g. "racecar" type in "t/lifecycles/utils.pl").
