This should not be possible

Describe the bug
Calling procedure with CommandBehavior.SchemaOnly behavior wraps sql with SET FMTONLY ON and SET FMTONLY OFF lines which results in following errors:

// for fully-qualified name (db.schema.proc)
Attempt to locate entry in sysdatabases for database 'SET FMTONLY ON
TestDataCore' by name failed - no entry found under that name. Make sure that name is entered proper

the shared_storage_type terraform variable has been removed recently but some dead references can still be found throughout the project.

supersedes #286
