suggester (suggester.build) -> request for async call

I would like to request a async call to build suggester.

At the moment (as per: https://solr.apache.org/guide/8_10/suggester.html ) the only way to manually trigger the build of suggester is to issue /suggest query with suggest.build=true.

This call is syncronous, on some bigger collections we have, we get timeouts from clients etc as it can last a few minutes... A perfect solution to this issue would be to have an option of async call identical to backup api: https://solr.apache.org/guide/8_10/making-and-restoring-backups.html where there is a requestID which can be checked from time to time (we use this a lot and this has improved stability of our processes a lot)
