Enabling minimal support for as-yet unsupported Teiid versions

Since there is only one teiid-client plugin which is responsible for all versions of teiid instance support, there is no longer any point in specifying versions that the plugin supports.

Thus, update the plugin to establish levels of support for versions of Teiid, ie. no support, full support and works-but-no-support. This should allow versions of Teiid that have not yet been fully integrated and tested to be connected to by the client.
