Add phosphor-fan-monitor init service

Updated the phosphor-fan-monitor service file to invoke the fan
monitoring application in 'monitor' mode (actively updating the
functional states of fans).
Created a phosphor-fan-monitor-init service to invoke the fan monitoring
application in 'init' mode where the fans are set to functional, such as
at poweron.

Resolves openbmc/openbmc#2187
