The utils.setup_django() costs a lot of time, but both update.py and
update_layer.py call it, so move layer validation from update_layer.py
to update.py to avoid calling update_layer.py when possible can save a
lot of time.
Now we don't have to call update_layer.py in the following cases:
* The branch doesn't exist
* The layer is already update to date on specified branch (when no
reload)
* The layer dir or conf/layer.layer doesn't exist
We can save up to 98% time in my testing:
$ update.py -b master --nofetch [--fullreload]
Before Now Reduced
No update: 276s 3.6s 98%
Partial update: 312s 87s 72%
Full reload: 1016s 980s 3%
Note:
* All of the testing are based on --nofetch
* "No update" means all layers on the branch is up-to-date, for
example, when we run it twice, there is no update in the second run,
so we only need about 3s now, which is the most common case when we
use cron to run it per half an hour.
* "Partial update" means part of the layers have been updated.
* "Full reload" means all of the layers have been updated.
