Move to a simpler journal based synchronization

Removes the old find all updated -> update -> find all deleted ->
delete workflow and replaces it with one that tracks the journal
better.
Enable full and project based synchronization

By project synchronization is useful to manually force a particular
project to update itself. Full is useful especially as a catch all
run once a day or so command just to make sure nothing got lost
in the shuffle.
Update Pylint config to not error on too many return statements
Remove a no longer used setting

With the removal of eventlet there is no longer a mechanism for
timing out a synchronization.
Fix trigger to correctly normalize projects.name

Without the g flag on regexp_replace PostgreSQL only replaces
the first match (apparently). Using the g flag has it replace
it across the entire string.
Query by normalized instead of name

Querying by name causes a clash in the unique field normalized
when someone deletes a project and recreates it with a differently
cased name. This update will have it search by normalized instead.
However to ensure that an update isn't being applied to a project
with the wrong name we assert that the name matches.
PEP8
Remove a now unused method on fetcher
