RHSM proxy can be down, users will never now

[Emilien Macchi]

When using rhel_reg_http_proxy_* parameters for RHEL subscription, TripleO will never check if the proxy is actually available. If it's not, it will fail and the poor user will never know why (it will probably timeout).

TripleO could be nice and fail early if the proxy isn't ready, and send a nice message so the user knows what to do.

    RHSM: when using proxy, test its connectivity first

    When using RHSM with a proxy, we want to make sure the proxy can be
    reached. This patch verify that a tcp socket can be open from the client
    to the proxy.

    This patch also does a bit of refactoring:
    - --retry-delay 10 --max-time 30 is now used in a parameter everytime we
      use curl.
    - proxy options are now used everytime curl is used, even for detecting
      which version of Satellite is running, now we use proxy options.
