    Refactor ris-rest infrastructure

    This patch refactors the rest infrastructure in ris in
    following ways:

        - Includes ``retrying`` package to retry on redirection
        - Modularized the rest infra code
        - No behaviour change as such barring the log output

    Partial-Bug: 1646685

    Separate out rest infra from ris

    This patch is again targeted towards support of consuming
    Redfish APIs. ReST infrastructure has been separated out from
    RIS module to be used by both RIS and Redfish portions.

    Initial redfish commit

    This patch is again targeted towards support of consuming
    Redfish APIs. This introduces the initial commit for redfish
    related files. Till now, the redfish code base is **not** yet
    instrumented to be called from ``ilo.client.IloClient`` object.
    A separate patch will be submitted to instrument this redfish
    code for Gen10. Till that this patch turns out to be a
    pre-enablement of redfish on proliantutils.

    Instrumenting redfish into proliantutils' client

    This patch introduces the instrumentation of redfish object's
    method invocation from ``ilo.client.IloClient`` object. When
    a method is invoked on client, based on the target hardware
    the execution of that corresponding method bestows on RIBCL,
    RIS or Redfish. Again, when the context is Redfish then there
    RIBCL can remain enabled/disabled. In case of RIBCL enabled,
    we fall back to RIBCL for any method invocation which is not
    (yet) implemented in Redfish. For RIBCL being disabled, we
    raise ``NotImplementedError``.

    This also introduces a parameter in client constructor named
    'use_redfish_only' which when set to True will force the use
    of redfish. Default value is False.
