Andre Mauricio Zelak 06c396fbe3 Fix HA clock selection algorithm
The issue reported is a particular case of a BC configured with
redundant PTP clocks with same priority. When a clock recovers
from a failure, as both clock were configured with same priority
it's expected the active clock source to remain active. But if
the recovered clock presented a better local clock class than
active, it was being selected active. This specific case was fixed.

Closes-bug: 2084723

Test plan: BC with same priority
PASS: Start the PTP service with all clocks out of requirements,
one is selected, no matter which one.
PASS: Then, when the backup clock recovers from failure it is
selected active.
PASS: Then, when the other clock recovers from failure it remains
as backup, no matter the local clock class.
PASS: Then, when the active goes out of requirement, the backup
is set active.

Test plan: GM with same priority
PASS: Start the PTP service with all clocks out of requirements,
one is selected, no matter which one.
PASS: Then, when the backup clock recovers from failure it is selected
active.
PASS: Then, when the other clock recovers from failure it remains
as backup, no matter the local clock class.
PASS: Then, when the active goes out of requirement, the backup
is set active.

Subject: [PATCH 52/61] Command 'valid sources'
The 'valid sources' command is used to get a list of interfaces which
the clock is matching the requirements. The response contains a space
separated list of interfaces, or "None" when not a single clock is
matching all the requirements.
Test plan: valid sources command
PASS: Verify that a space separated list of interface is returned when
one or more clocks match the requirements.
PASS: Verify that the string "None" is returned when not a single clock
match the requirements.
