New check: TLS identity verification

[blackandred]

Verification if curl -H 'Host: example.org' https://1.2.3.4 matches curl https://example.org certificate.
Reason: Manipulated man-in-the-middle proxy detection

Example:

{
    "type": "tls-integrity",
    "input": {
        "src_url": "1.2.3.4",
        "hostname": "example.org"
    }
}

Implemented.

Not implemented - the #20 was implemented. So this goes back to backlog for next release.
