SOLR-17066: Switch "LB" clients away from core URLs (#2283)
Providing a core URL String as a SolrClient's "base URL" prevents
it from communicating with other cores or making core-agnostic API
requests (e.g. node healthcheck, list cores, etc.)
This commit migrates usage of both "LB" clients away from using
raw core-URL Strings, in favor of using a new structured 'Endpoint'
class, which allows access to both the "root URL" and "collection"
separately.
This commit also updates various ref-guides and Javadoc snippets to
reflect the fact that clients now only accept "root URLs" (with a small
exception for LB clients which may use the Endpoint class, as mentioned
above).

> URL: https://issues.apache.org/jira/browse/SOLR-17066
> Project: Solr
> Issue Type: Improvement
> Components: SolrJ
> Reporter: Jason Gerlowski
> Priority: Major
> Time Spent: 12.5h
> Remaining Estimate: 0h
>
> Currently, URL-driven SolrClients can consume a base URL that either ends in
> an API-version specific path ("/solr" for v1 APIs, "/api" for v2), or in the
> full path to a specific core or collection ("/solr/techproducts").
> The latter option causes a number of problems in practice. It prevents the
> client from being used for any "admin" requests or for requests to other
> cores or collections. (Short of running a regex on
> {{SolrClient.getBaseURL}}, it's hard to even tell which of these restrictions
> a given client might have.) And lastly, specifying such core/collection URL
> makes it tough mix and match v1 and v2 API requests within the same client
> (see SOLR-17044).
> We should give SolrJ users some similar way to default collection/cores
> without any of these downsides. One approach would be to extend the
> {{withDefaultCollection}} pattern currently established in
> {{CloudHttp2SolrClient.Builder}}.
> (IMO we should also revisit the division of responsibilities between
> SolrClient and SolrRequest implementations - maybe clients shouldn't,
> directly at least, be holding on to request-specific settings like the
> core/collection at all. But that's a much larger concern that we might not
> want to wade into here. See SOLR-10466 for more on this topic.)
