Convert sa-prod/solr from NAS to local node storage

[decimalator]

Descriptive summary

When we start work on #2319 we should also convert sa-prod/solr from using NAS storage to using local worker node storage.

SOLR is only as fast as its disk storage. The drawback to using networked storage for SOLR is that it adds a little extra latency to each request. The benefit is that SOLR can continue to run all of its replicas if one of the worker nodes currently running SOLR needs to be brought offline. With 3 replicas that isn't really an issue the vast majority of the time.

Expected behavior

sa-prod/solr-N Pods mount their data storage from their local worker node.

Actual behavior

sa-prod/solr-N Pods mount their data storage from nas-fast
