add 'onefuzz debug log tail'

[bmc-msft]

Adds onefuzz debug log tail <keyword>, which enables performing the same component in onefuzz debug log keyword <keyword> in a loop.

Optimizations:

• only returns the N records at a time (default 1000)
• each query only returns records that occur after the latest record received.
• If no results are returned, waits 10s before retrying
• Increases the wait time by 1.5x until the wait time is larger than 60s

Using --filter provides the ability to filter each record that comes back via jmespath.

Example uses:

Monitor any log messages (which ignores metrics) for a given job_id GUID

onefuzz debug logs tail bf4efdfd-685c-444a-81c5-d911477433ae --filter message

Log the job_id and task_id for each new unique report:

onefuzz debug logs tail new_unique_report --filter '[customDimensions.job_id, customDimensions.task_id]'

Log the job_id and task_id for each new unique report only for the specific job_id:

onefuzz debug logs tail "new_unique_report d5bcd4d2-4dab-49d5-a215-66db94fb0309" --filter '[customDimensions.job_id, customDimensions.task_id]'
