RFC8555 requires that most requests contain "kid" field in the
protected header. The JWK version is still used for new account
creation and certificate revocation requests. Previously,
in earlier drafts JWK variant was used exclusively.
While JWK is computed based off the account public key,
the new "kid" field takes literal value of the Account URL
provided by the CA during a new registration. The actual support
for KID-based JWS requests in Client will be added in a follow up CL.
For what concerns the existing behaviour of JWS requests,
a new field "url" is added to the protected header.
Before:
{"alg":"...", "jwk":"...", "nonce":"..."}
After:
{"alg":"...", "jwk":"...", "nonce":"...", "url":"..."}
where the new field takes a value of the target request URL.
This still works for CAs supporting pre-RFC protocol versions.

Currently, only rsa.PrivateKey and ecdsa.PrivateKey are supported
when creating JWS signatures. However, it is unnecessarily limiting
because any crypto.Signer implementation can sign a digest
in the appropriate format.
This change uses key.Public() instead of type-asserting the private
key which allows for a custom crypto.Signer implementation.
For instance, a key stored in a hardware module where the latter
does the actual signing without the key ever leaving its boundaries.
