Commit b2e1f8ed4a309531d62125319501b313ac39605b in solr's branch

SOLR-18130: new param "solrConnection" in solrj-streaming, support HTTP (#4320)
SOLR-18130: Universal SolrCloud connection string support (HTTP/S and ZooKeeper)
Introduced a universal Solr connection string for SolrCloud connections in
multiple places:
streaming expressions, CLI, JDBC driver, cross-collection joins.
Connections can now be configured via HTTP(S) without requiring ZK dependencies
and connectivity.
"zkHost" is deprecated in lieu of "solrConnection" in most places.
Notable changes:
- SolrJ: added CloudSolrClient.Builder(CloudSolrClientConnection) overload;
renamed isZk to isZookeeper in the CloudSolrClientConnection record; added
toString() to produce the canonical connection string
- SolrJ Streaming: added solrConnection param to all streaming functions
(zkHost is deprecated but still supported); added withDefaultSolrConnection
and withCollectionSolrConnection to StreamFactory; buildSolrConnection
promoted to an instance method
- SQL JDBC driver: supports HTTP-based JDBC URLs alongside ZooKeeper-based ones
- CLI tools: added --solr-connection option; -s short flag now maps to
--solr-connection instead of --solr-url (backwards compatible)
- Join Query Parser: added solrConnection parameter to cross-collection joins

> Project: Solr
> Issue Type: Improvement
> Components: SolrJ, streaming expressions

> Fix For: 10.1

> In the SolrJ streaming expressions module, CloudSolrStream depends on
> ZooKeeper, and thus so does its subclasses (DrillStream, TopicStream,
> ShuffleStream, ParallelStream). It's a runtime dependency, triggered by a
> "zkHost" parameter that's supplied to {{SolrClientCache#getCloudSolrClient}}
> that uses {{CloudSolrClient.Builder}} that uses reflection to try to load
> {{ZkClientClusterStateProvider}}.
> I propose renaming these parameters in the module from zkHost to maybe
> "quorumHosts" that could either be list of Solr HTTP (when it starts with
> "http:" or "https:") or ZK if not. This should bring about a new
> well-deserved constructor to CloudSolrClient.Builder to parse a string, as
> it's not a matter specific to streaming expressions. This would be very
> convenient to callers I've seen elsewhere.
