> If we want to look up the PTable of a tenant view we currently need to create a tenant specific connection and call {{PhoenixRuntime.getTable()}}. This could be inefficient if we need to create millions of tenant specific connections.
> We could instead just pass in the tenant id and use a global connection
>  {{getTable(Connection conn, String tenantId, String fullTableName, long timestamp)}}
> Insread of using the scn from the connection to set the clientTimestamp, we would use the passed in timestamp.
> If the table isn't cached we would need to make a rpc to fetch the table from SYSTEM.CATALOG
> {code:java}
> MetaDataMutationResult result = new MetaDataClient(pconn).updateCache(PName tenantId, String schemaName, String tableName)
> {code}
