Context
Similar to the work done in #3416, I first upgraded Solr to v8.0 off this branch.
There was an error arround
solr.StandardFilterFactory. This is apparently a no-op and hasn't been doing anything since Solr 3.1 as mentioned here.We can safetly remove this as a result.
With this option removed, Solr v8.0 worked just fine. I upgraded then to Solr v8.11.X and everything continued to work as well.
I also compared what Hyrax did to get to Solr v8 and they took the same approach for this.
Solr v8.11 is the oldest version to still be supported and is not end of life. So this version will get us critical security updates.
NOTE: Leaving this in DRAFT until #3416 is merged first and production Solr index has been reindexed on Solr 7.
