Configuration number comparisons

[arlimus]

When running against a configuration file with numbers, e.g. ssh_config with:

Port 22

The test would have to be written:

its('Port') { should eq '22' }

However users also expect to be able to write:

its('Port') { should eq 22 }

It would be great to find a way to reconcile this and help users to write the test they expect.

with #318 it is possible to write:

describe sshd_config do
  its('Port') { should cmp '22' }
  its('Port') { should cmp 22 }
end
