SOLR-17955 & SOLR-17437: OTEL metrics: SplitShardCmd.checkDiskSpace needs
conversion (#3859)
Fixes split shard which was disabled after moving metrics to OTEL. Split shard
now parses and reads prometheus metrics for disk space on the correct node for
the split shard command. Also a minor change to throw when failing to get the
index size and free size metrics.
> Shard splits no longer check for sufficient disk space

> Key: SOLR-17437
> URL: https://issues.apache.org/jira/browse/SOLR-17437
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 9.3
> Reporter: David Smiley
> Priority: Minor
> Labels: newdev
>
> SolrCloud shard splits check for sufficient disk space. After the SOLR-16507
> refactoring, the metrics request is no longer routed to the pertinent node;
> instead it's evaluated at some arbitrary node or maybe the Overseer. It
> doesn't find the size because it can't find the replica on that node (unless
> it actually is there). Then logs a warning: "cannot verify information for
> parent shard leader". This behavior can be verified by modifying
> SplitShardTest to use a nodeCount of 2 and then look for this warning.
> Maybe we should add an "assert false" here in addition to the fix. IMO
> doesn't need a dedicated test but SplitShardTest could use an additional node
> for nightly runs.
> -When this is fixed, probably use SolrCloudManager after SOLR-16503. If that
> has not been done yet (as of this writing is not), then the current way is to
> call SolrRequest.setBasePath.-
