[Bro] Disable some type of "alerts" for internal servers

[C.L. Martinez]

Hi all,

  I am receiving a lot alerts like this:

  Bro SSL::Invalid_Server_Cert. 172.16.129.8 (Unknown):3040 -> 
172.17.0.130 (Unknown):1610

  which it is correct: we are using a lot of certs auto-signed in our 
infrastructure.

  Is it possible to disable this type of alert for an IP or a group of IP's?

Thanks.
