This is the first step of several to remove PKI token support in
keystone. A large issue in removing PKI support is support for the
revocation list must be maintained.
This patch removes support for the token format, it's surrounding tests
and examples that are generated. Additionally, some wording has been
changed around the CLI and config options to make the distinction
between keys and certs used for PKI tokens and those used for getting
the revocation list (a list of tokens that are revoked, which is signed).
Future patches will:
- Remove the keystone-manage commands for generating certs
- Modify the revocation list (at /auth/tokens/OS-PKI/revoked) to return
a 403 if pki is not configured (instead of raising a 500). We cannot
remove the API as that would break an API contract.
- Options to configure PKI will be marked as deprecated
- If PKI is configured a normal signed list will be returned (same
behavior as today)
- Follow up patch to keystonemiddleware will make sure auth_token does
not rely on the revocation api at all.
