support TLS auth

[toxic0berliner]

I already have a LAPI running and my firewall is blocking based on crowdsec decisions. Nonetheless I 'm interested in your setup to catch and parse the ha logs appropriately (for brute force today I understand)
But I have no API key I only use a certificate to authenticate either a bouncer or an agent to the LAPI.
Would be great for me to be able to pass a cert&key as well as the CA authority signing the cert of my LAPI to be able to use this plugin out of the box.
