Fixes #695 - inconsistent use of domain name in LLDP

[ktbyers]

Cisco had an inconsistent use of domain name in LLDP brief (as compared to other IOS devices). This was causing a failure.

@bdlamprecht Please review the test data that I included here and make sure you are okay with me including it (I scrubbed it a bit).

Wow, that's a great turnaround time, much better than I anticipated!

I see you changed the domain names and such, but I'd prefer to clean up some of the hostnames, IPv4 , and IPv6 addresses as well since this is going to be publicly available for the foreseeable future.

The specific strings that I'd request to be altered are the following:
bld-XXX-XXX to 000-XXX-XXX (or something simliar, just remove the bld part)
and
9.88.X.X to 10.0.X.X
as well as
2620:1F7: to 2001:DB8:

I'm happy to cleanup the test data if you'd like me to. Let me know.
Thanks again!

@bdlamprecht Okay, see updated strings in the test data. Just let me know if anything else needs updated in the test data.

Coverage increased (+0.02%) to 78.943% when pulling 88f8f36 on lldp_fix_blamprecht into c55c7c0 on develop.

That looks good, except you missed the line with the Port Description: bld/XXXX.

[ktbyers]

@bdlamprecht Okay, fixed.

[bdlamprecht]

Great, that looks good. I appreciate it very much!

+1 from me. Ran into this issue yesterday when writing a tutorial and using an old switch. This PR fixes the issue.

Please merge. :)
