cim_operations EnumerateInstances

[KSchopmeyer]

Code optionally gets namespace from ClassName parameter but documentation is unclear about this.

      ClassName (:term:`string` or :class:`~pywbem.CIMClassName`):
        Name of the class to be enumerated, in any lexical case.
        If specified as a :class:`~pywbem.CIMClassName` object, its host
        component will be ignored.

This issue actually applies to all four EnumInstance operations (ein, ei, oein, oei).

Because the description of the namespace argument already describes the full story for namespace defaulting, I suggest that the ClassName argument just clarifies that its namespace component does play a role for namespace defaulting, and otherwise refers to the namespace argument.

Proposal:

Change the text:

If specified as a :class:`~pywbem.CIMClassName` object, its host
component will be ignored.

To:

If specified as a :class:`~pywbem.CIMClassName` object, its namespace
component will be used as a default namespace as described for the
namespace argument, and its host component will be ignored.

This proposal should be picked up by PR #320 as far as the pull operations go, but it should also be applied to EnumerateInstances() and EnumerateInstanceNames().

PR #320 does address this.
