Ruby bindings RFE: libdnf5 modules and classes should be namespaced.

[jackorp]

While not necessarily a problem, the current lack of namespacing in Ruby does not seem too great to me.

For example Common module is a global constant upon requiring libdnf5/common. I think having a prefix so that it becomes for example LibDNF5::Common (or Libdnf5::Common, or other variations of capitalization) would be better.

I'd apply this to all modules present, but names such as Logger, Common, or Base are IMO more probably to have a clash in other projects than for example Rpm.

There could be a small problem with compatibility, but if LibDNF5 is a module only used for namespacing (with no additional/new methods on it), then it can be included in the global namespace guilt-free:

require 'libdnf5/base'
include LibDNF5

base = Base::Base.new()
