[WiFi] Replace uptime counter with timestamp

[xavier-contreras]

Change Scope

This changes the leaf "uptime" under openconfig-ap-manager.yang from a uint32 counter to a new leaf of "up-time" which will be a timeticks64. This is to make telemetry ingestion less churn heavy. The intent of the leaf does not change.

This change is not backwards compatible as a leaf is replaced.

Platform Implementations

oc-types:timeticks64 is used throughout other models and it should be trivial to implement.

Should we move this to the new release model: https://github.com/openconfig/public/blob/master/doc/releases.md ?

If we follow this, would should aim to mark uptime as deprecated and introduce up-time.

Agreed, this is a good example where we can deprecate the leaf to make this change non-breaking.

Fixed -- guidance did not exist prior to this PR, good to see it documented. I also updated the version to minor increase since this is no longer a breaking change.
