Integrate of develop did resolution for did method did:web

[francis-pouatcha]

Spec at https://w3c-ccg.github.io/did-method-web/

It can be implemented as a sub-module of the did-utils project

[francis-pouatcha]

Simple path testing on an existing online server

There is a unit test in the code base just testing if the server is responding. Could be extended to test if document returned is a did server.
