This commit adds support for certificate revocation status by Certificate
Revocation List (CRL) in Prometheus.
New fields 'CRL' and 'CRLFile' have been added to the Prometheus config
('tls_config' section). These enable certificate revocation validation
with the provided CRL.
The Prometheus loads the Certificate Revocation List (CRL) to validate the
revocation status of the peer's certificate chain by invoking the
'verifyPeerCertificate' (https://pkg.go.dev/crypto/tls) function during
a TLS handshake.

Move and separate version-sensitive functionalities related to CRL into two go files within the config package so that it can build with the corresponding go version. Signed-off-by: Ziqi Zhang <ziqi.zhang.ext@ericsson.com>

@roidelapluie Hi, Julien. |

I think that CRL is questionable: the fact we have to implement it ourselve is prone to add security bugs, additionally, there are concerns about CRL in general by the crypto/tls author itsels: https://www.imperialviolet.org/2014/04/19/revchecking.html What about we implement this when the go team decides to implement it in crypto/tls ? |
