Steal based on HTTP Path Filter

[aviramha]

Currently we support filtering based on HTTP headers. Some of the users asked to support stealing based on the path accessed.

• merging HTTP Path Filter #1550
• adding to operator

We probably need to deprecate the old filter config, since it's "explicitly" http header. Having said that, would we want the filters to be or / and / or mutual exclusive? like if user specifies a http header filter and path header, should it be matching both or only one or should we just error for now?

Personally I don't see a use case for either, and would rather error out until a user asks for it than support a use case we don't understand.
