Address ENG-10695, ENG-8227, as well as a few minor improvements.

• Renamed logs monitoring functions to be more accurate
• Cached last value, so if the connection is closed and then reopened, logs monitoring continues as expected
• Disabled logs monitoring in clearSensitiveData
• Moved primary device check to the place where DB is initialized and operational, instead of doing it for each log which was inefficient

Depends on D14837

Verified that logs upload works:

• Checked that logs start to be uploaded after compaction is created
• Checked that logs start to be uploaded after successful restore
• Checked that logs are not uploaded after restoring on secondary device
• Checked that logs are not uploaded when primary device is logging out
