KUDU-1942. Kerberos fails to log in on hostnames with capital letters

This ensures that servers canonicalize their FQDNs to lower-case before
generating Kerberos principal names.

With this change I was able to set up a working cluster on my laptop
with a capitalized hostname, where before it would fail as described in
the JIRA.

I also verified that I was able to connect from both C++ and Java
clients.
