charm-barbican doesn't use worker-multiplier to set up wsgi processes

[Nobuto Murata]

At this moment, the charm has a hard coded value as processes=3 threads=10 unlike other charms. Would be nice to configure it dynamically based on the config specified as worker-multiplier.

charm-barbican (master=)$ git grep processes= src/templates/rocky/barbican-api.conf
src/templates/rocky/barbican-api.conf: WSGIDaemonProcess barbican-api user=barbican group=barbican processes=3 threads=10
src/templates/rocky/barbican-api.conf: WSGIDaemonProcess barbican-api-admin user=barbican group=barbican processes=3 threads=10

Also, barbican-worker has only one process, it seems it's not following worker-multiplier either. But I'm not sure if it's a good idea to run multiple processes in parallel.

pgrep -af barbican-worker
289 /usr/bin/python3 /usr/bin/barbican-worker --config-file=/etc/barbican/barbican.conf --log-file=/var/log/barbican/barbican-worker.log
