@JamesRTaylor @twdsilva also, do we really want to avoid calling
ensureTableCreated from createTable in case it is a system table? Apart from
actually ensuring that the table is created or not and the client-server
compatibility checks, this method also modifies the table according to a new
descriptor (I don't have enough background as to why we do this here). Any
advice guys?

> Currently we create/modify Phoenix meta tables on first client connection.
> Adding a property to make it configurable (with default true as it is
> currently implemented).
> With this property set to false, it will avoid lockstep upgrade requirement
> for all clients when changing meta properties using PHOENIX-4575 as this
> property can be flipped back on once all the clients are upgraded.
