acme: support RFC 8555 account management

Most important change in this CL is that Client is now able
to correctly format and sign requests in KID form with a valid
"kid" value.

According to the RFC, most requests must include KID field
in the protected head of JWS requests. The KID value is the account
identity provided by the CA during registration.

The KID value is also the Account URL. Hence, the CL is tied to
account management.
