[Hawkular-dev] travis secure entries in the travis.yml

[Jiri Kremser]

Hello,
  as you probably know travis allows to encrypt a secret in the travis.yml. I am not going to question how super secret it is, but could we please add a comment on those lines to know what env property it encodes?

Now, it's almost impossible to find out which line is safe to delete in here:

I believe there are some unused lines.
