Description

We are having discussion on multiple jiras for requests for Collections apis from UI and how to improve them:

SOLR-9818: Solr admin UI rapidly retries any request(s) if it loses connection with the server
SOLR-10146: Admin UI: Button to delete a shard
SOLR-10201: Add Collection "creates collection", "Connection to Solr lost", when replicationFactor>1

Proposal =>

Phase 1:

Convert all Collections api calls to async requests and utilise REQUESTSTATUS to fetch the information. There will be performance hit, but the requests will be safe and sound. A progress bar will be added for request status.

> submit the async request
if (the initial call failed or there was no status to be found)
{ report an error and suggest the user look check their system before resubmitting the request. Bail out in this case, no retries, no attempt to drive on. }
else
{ put up a progress indicator while periodically checking the status, Continue spinning until we can report the final status. }

Phase 2:

Add new buttons/features to collections.html

a) "Split" shard
b) "Delete" shard
c) "Backup" collection
d) "Restore" collection

Open to suggestions and feedbacks on this.
