Add key from internal Jenkins
Update pip to make it work behind proxies
Refactor hiera config

remove user specific hiera files: harish

refactor address and interface based lookups
to have a single definition of those things
in the env specific files.
Simplify data configuration

- removed explicit defition of db_name and
updated the module default so that it defaults
to $name (this is already hard-coded on the
clients)

- removed intermediary rjil::openstack::db_*
parameters which did not actually map to any
classes.
