Add source fully qualified name extension properties

To support TEIIDTOOLS-362 and in general the lookup of source objects by a name other than the Teiid name, we need to add a fully qualified name property.

The proposal would look like an ldap name containing both the name/parts:

create foreign table "schemaName.tableName" (...) options ('teiid_rel:fqn' 'catalog:catalogName/schema:schemaName/table:tableName');

The names will reflect the constructs for each source:

google: 'worksheet:name/sheet:name'
salesforce: 'sObject:name'
etc.
