Title: Preview VDB Cleanup on server version change

* Since preview vdbs can contain metadata incompatible between server
versions, a change in the default server version must require all preview
vdbs to be delete and rebuilt against the new default server

* Preview manager should not be disconnecting the teiid server. As a
background service this can cause confusion for the user
