tags do not work with az lab vm create

[claasd]

Describe the bug When using --tags with lb vm create, a error message Parameter 'tags' must be of type '{str}' is thrown.

I tried different escaping methods, none of them worked.

Parameter 'tags' must be of type '{str}'

Expected behavior The VM should be created with the tag set, no exception is thrown.

Confirmed this is a bug. Tags are not registered properly in params.py
