fix rhsmd.processTimeout support

[vchepkov]

It seems even though documentation shows camel case of the parameter it reports it in lowercase:

# subscription-manager config --list
[rhsmd]
   processtimeout = [300]

also seems puppet resources attributes can't be uppercase either

Had to fix some comments to keep robocop happy

I don't think this is caused by my change and I am not sure how to fix it
