Ticket 49218 - Certmap - support TLS tests
    
    Bug Description:  This adds support for pluggable certificate
    mapping libraries. To achieve this, this replaces the existing
    baked in certificate mapping code.
    
    Fix Description: Improve our tls tests to cover more cases,
    support external signing cas, user certs, and addition of
    TLS by default to tests.
