This adds the HTTP client as discussed in #516

Note that this is a breaking change because of the semantics of the DIDWeb struct:

  • Currently, DIDWeb is an empty struct and can be instantiated as DIDWeb by itself (no {} needed), and appears in various places as &DIDWeb.
  • This change requires DIDWeb to be instantiated via methods DIDWeb::new_with_default_http_client (this is the drop-in replacement for existing functionality) or DIDWeb::new_with_http_client (if you want to specify your own HTTP client).

I altered the various call sites that were using &DIDWeb, and changed them to use an instance created with DIDWeb::new_with_default_http_client. However, codebases downstream of ssi that use DIDWeb will need to update their uses of DIDWeb (e.g. when constructing a DIDMethods) in order to integrate this change.

…r resolution.

DIDWeb struct has an HTTP client to use for DID resolution.  It's incredibly slow to create a new
reqwest::Client, due to the overhead of loading the system's root certificates.  This HTTP client must
be specified by constructing the DIDWeb instance using new_with_default_http_client (to use defaults)
or DIDWeb::new_with_http_client if there is an specific reqwest::Client that should be reused.
Note that this is the recommended approach to using reqwest::Client (see
https://docs.rs/reqwest/latest/reqwest/struct.Client.html).

Same deal here, I sent in a signed CLA Oct 6, 2021, but let me know if you need a new one for whatever reason.
