Config parameters for timemaster service

timemaster service provides HA between different
time service i.e chrony, PTP. When timemaster service runs,
it spwans instances/child processes of chronyd, ptp4l and
phy2sys. Look at below output.

Timemaster service uses /etc/chrony.conf and /etc/ptp4l.conf to create
runtime instance for these 2 timeservices. These 2 time services sync to
their respective time source. Timemaster provides HA between chrony
and PTP (between different PTP domains as well which is not part of
this patch).Timemaster compares all time sources and use the best
sources to synchronize the system clock. if chronyd commuication breaks
then timemaster will set system time with PTP grand master's provided
time and vice a versa.

2 new parameters added by this patch in order to make above work.

In order to use timemaster service, we need to remove Timesync and
add TimeMaster in roles_data.yaml for the role we desire to have
Timemaster service.
