We have some unexpected/unexplained Telemetry session data resets (at least for the profileSubsessionCounter).

We need to track the save & load failures for the session data file to investigate.

Add probes for Telemetry session data load & save failures

Approval Request Comment
[Feature/regressing bug #]:
Telemetry Unification
[User impact if declined]:
This adds diagnostics for when we fail to load or save persisted session data - we need this for validating the incoming data and detecting issues.
It is part of a mostly fixup & diagnostic uplift batch for 41: http://bit.ly/1LYhA16
[Describe test coverage new/current, TreeHerder]:
We have automated test-coverage, it baked on Nightly, we are monitoring it.
[Risks and why]:
Low-risk, we haven't seen anything crop up on Nightly here.
[String/UUID change made/needed]:
None.

[Triage Comment]
Fix has automated tests, and code has been in Nightly for a week so should be safe to uplift to Beta.
