Make worker-multiplier sane in container environments
Resync charm-helpers to pickup the capped worker-multiplier
changes when deploying in containers.
Drop the default value for worker-multiplier of 2.0; this
is now handled from within the codebase rather than via a
default configuration value, reflecting the differing
behaviours between container and non-container deployments.

Bug description:
On containerized setups with multiple cpus and hyperthreading on the
metals the containers can see a large number of cores. With the
default worker multiplier settings this eg. results in 112 workers
plus a leader processes on one of our installs. With HA we have then
3x113 processes serving in total, which is a bit of a waste (3x16G of
RSS for one service, as an example)
While this can be tuned down I'd suggest to cap the number of workers
when the worker-multiplier setting is on default to make this more
sensible out of the box
