Adding setup.cfg to configure command for rpm build

[lukas-bednar]

In order to build rpm for this library, it requires adding dependency to build proper rpm package.

Coverage remained the same at 61.36% when pulling d7a20f7 on lukas-bednar:setup_bdist_rpm into 3da6bec on diyan:master.

@lukas-bednar PR merged. What about python-kerberos optional dependency? Can we somehow flag it as optional/recommended/whatever in rpm package?

[lukas-bednar]

@diyan unfortunately rpm-spec file doesn't provide option to include optional-dependency.
you can require dependency and it will get installed, or do not require it and it will not get installed, nothing between.

on other hand it would be possible to create meta-rpm which just groups several packages together, so it could be pywinrm + python-kerberos.

anyway I think it is not rpm's approach, when you need to use something extra / enable some feature, you do it explicitly. for example httpd & mod_ssl . you want to use SSL/TLS module for you Apache, you have to install mod_ssl explicitly and configure it accordingly.

@lukas-bednar Clear. Thank you for explanation.
