Remove metrics history from solr-core

The metrics history functionality doesn't need to be in solr-core, nor in Solr. For historical aggregations, users should use specialized solutions like InfluxDB, Prometheus etc.

While SOLR-14651 attempts to disable it better, I think we should ideally get rid of this feature completely. In the worst case, we could attempt to move it away from the solr-core and move it into a package.
