Configure systemd CPUShares/CPUQuota for fm-api.service

Browse Source 
fm-api.service CPUShares is reduced to 512 out of 1024 since
it exhibits severe CPU hog behaviour for extended periods.

This is part of an overall set of adjustments are required for systemd
cgroups CPUShares, CPUQuota, and AllowedCPUs for key system services.
This will improve latency of Kubernetes critical components, and
throttles lesser important services.
