[Ltib] ppp wget authentication

[Mike Goins]

I maintain a local gpp and ppp.  I use the gpp for FOSS items and keep
a few vendor items in the ppp.  This allows the gpp to be publicly
available, but the ppp is only accessible on the company network.
However, I would like to put some sort of authentication on the ppp
and make it external facing.   This would allow moving my continuous
integration systems off-site.

There doesn't appear to any method to put credentials in ltib, so I am
looking at a way to add. What I have come up with so far.

Add new configs to .ltibrc to allow site specific opts:
%gpp_opts
%ppp_opts

In get_remote_file(), since it iterates over the pp list, append these
options to the wget_opts.


Seem OK?  Has anyone else used or tried authentication?


Side note:   Shouldn't ltib be setting the WGETRC environment variable
anyway, even if to a non-existent location?   ltib uses the host built
/opt/ltib/usr/bin/wget, so it would seem prudent to avoid getting the
user's .wgetrc which may interfere with the the parameters ltib has
set up or add parameters that ltib "skips".
