SOLR-17697 Implement picocli for create and delete commands

[janhoy]

Usage: solr create [-hvV] -c=<name> [-d=<confDir>] [-n=<confName>] [-rf=<replicationFactor>] [-sh=<shards>] [-u=<credentials>] [-s=<solrUrl> | -z=<zkHost>]
Creates a core or collection depending on whether Solr is running in standalone (core) or SolrCloud mode (collection).
  -c, --name=<name>          Name of collection or core to create.
  -d, --conf-dir=<confDir>   Configuration directory to copy when creating the new collection; default is _default.
  -h, --help                 Show this help message and exit.
  -n, --conf-name=<confName> Configuration name; default is the collection name.
      -rf, --replication-factor=<replicationFactor>
                             Number of copies of each document across the collection (replicas per shard); default is 1.
  -s, --solr-url=<solrUrl>   Base Solr URL, which can be used to determine the zk-host if that's not known.
      -sh, --shards=<shards> Number of shards; default is 1.
  -u, --credentials=<credentials>
                             Credentials in the format username:password. Example: --credentials solr:SolrRocks
  -v, --verbose              Enable verbose mode.
  -V, --version              Print version information and exit.
  -z, --zk-host=<zkHost>     Zookeeper connection string; unnecessary if ZK_HOST is defined in solr.in.sh; otherwise, defaults to localhost:9983.

Usage: solr delete [-fhvV] [--delete-config] -c=<name> [-u=<credentials>] [-s=<solrUrl> | -z=<zkHost>]
Deletes a collection or core depending on whether Solr is running in SolrCloud or standalone mode.
  -c, --name=<name>          Name of the core / collection to delete.
      --delete-config        Flag to indicate if the underlying configuration directory for a collection should also be deleted; default is false.
  -f, --force                Skip safety checks when deleting the configuration directory used by a collection.
  -h, --help                 Show this help message and exit.
  -s, --solr-url=<solrUrl>   Base Solr URL, which can be used to determine the zk-host if that's not known.
  -u, --credentials=<credentials>
                             Credentials in the format username:password. Example: --credentials solr:SolrRocks
  -v, --verbose              Enable verbose mode.
  -V, --version              Print version information and exit.
  -z, --zk-host=<zkHost>     Zookeeper connection string; unnecessary if ZK_HOST is defined in solr.in.sh; otherwise, defaults to localhost:9983.

Pull request overview

Implements picocli-based parsing/execution for the existing solr create and solr delete CLI commands, and wires them into the picocli-enabled solr entrypoint to support the new usage/help output shown in the PR description.

Changes:

• Register CreateTool and DeleteTool as picocli subcommands of SolrCLI.
• Add picocli option mixins/shared option groups (CredentialsOptions, ConnectionOptions) and implement callTool() paths for create/delete.
• Relax a packaging BATS assertion to accommodate picocli’s mutual-exclusion error wording.

• This warning suggests passing --force-delete-config, but the actual option defined by this tool is -f/--force (and there is no --force-delete-config). Update the message to reference the correct flag so users can resolve the warning.

          log.warn(
              "Configuration directory {} is also being used by {}{}",
              configName,
              inUse.get(),
              "; configuration will not be deleted from ZooKeeper. You can pass the --force-delete-config flag to force delete.");
        }
