Dag Wieers 4e6c113bf0 uri/win_uri: Make method a free text field (#49719)
* uri/win_uri: Make method a free text field

Since various interfaces introduce their own HTTP method (e.g. like
PROPFIND, LIST or TRACE) it's better to leave this up to the user.

* Fix HTTP method check in module_utils urls

* Add integration test for method UNKNOWN

* Clarify the change as requested during review
