Support multiple domain numbers for each uds socket used in HA phc2sys.
The ha_domainNumber option is an interface setting to configure
the domain number for an uds socket. It ranges from 0 to 127.
If the ha_domainNumber is not configured for a given interface,
the global domainNumber setting is used.
Test plan:
PASS: Verify use of ha_domainNumber configuration in manual
configuration.
Failure path: domain number match
PASS: Verify that phc2sys fails to start if domain number
doesn't match ptp4l instance parameter.
Regression:
PASS: Verify use of global domain number in manual configuration.
PASS: Verify auto configuration uses global domain number.
