Check if IM plugin is already deployed, if not deploy it
First we call activate endpoint that will return 404, or 202 and fill workRequestId
If activate call succeeded (202 and workRequestId returned), the next call to check_im will be checking the status
of the workRequest until it's completed. If work request fails, new activate call be we done at next backoff
interval followed by workRequest check. Once workrequest completed successfully,
osms_im_ready_flag_file gets created and check_im becomes no operation
Exponential backoff details
- after 10 backed off calls (now, 2/4/8/16/32/64/128/256/512/1024mins later), we try once 24hrs (every 1440mins)
