Bug Description

The worker-multiplier option is a convenience option that lets the users not worry about the number of CPUs specifically. However, in deployments where there are many containers running api services on the hosts, this results in way too many processes leading to high load.

Unfortunately, the worker-multiplier option is specified as an integer value which does not allow a user to reduce this below the number of CPUs detected.

A work around is to further spread the load to multiple baremetal machines and do not place all API services on the same machines.

    Change worker-multiplier to float

    Change the worker-multiplier to a floating point config option type
    instead of integer. This allows users to specify workers to be less
    than the number of CPUs, which is useful in deployments with multiple
    services deployed into containers on top of bare metal.

    The fix is to simply change the config option type and to sync in
    the necessary update from lp:charm-helpers.
