Provide debug flags for LDAP(s) connectivity

As an Administrator, I want to be able to set some additional flags to get very verbose tracing of the LDAP and LDAPS connection establishment process to debug various issues (loading of PEM file, TSL handshake, LDAP bind issues, ...).


This was possible in SafeLinx <= 1.1 using IBMs GSKit via the environment variables

LDAP_DEBUG=65535
LDAP_DEBUG_FILE=/tmp/ldap_trace.txt

which created logs similar to the one attached. Excerpt:

As newer version switched from GSKit to OpenSSL, this debug option, which is dearly needed, is missing. Please ad a similar debug/tracing option to future versions of SafeLinx.
