Ideal memory requirement for NameRes on Translator

[gaurav]

Some numbers on this issue:

• We have NameRes Solr set up with both a memory request and memory limit of 58Gi on both RENCI (Dev) and ITRB (CI, Test, Prod)
• Solr itself reports approx 2.30GB/58.00GB of JVM Memory used and 13.83GB/58.00GB of physical memory in normal use, but peaking at 26.61GB when running the babel-validation test suite.
• Kubernetes shows memory usage of 7.11Gi (WSS), 7.00 GiB (RSS) and 15.88 GiB (Cache), even when running the babel-validation test suite.

We are getting CPU-limited, so I'm going to try to increase our CPU limit first, and then see if we need to increase our memory limit.

This time we peaked at 2.57 CPUs, which means we had very slight (2%) of CPU throttling. Memory usage peaked at 6.83 GiB (WSS). However, we still had four requests time out. I should try to increase CPUs to e.g. 5 and see if that fixes it; otherwise, there might be some kind of Solr config we need to tweak.
