Adds some testing for Rex HTTP client lib

[todb-r7]

In light of PR #1476, it would be nice to have some basic,
maintained testing on Rex's HTTP Client proto library.

My rspec fu is quite weak, of course, but this should cover the very
basic cases. There are lots of pending holes, but hey, it's a start.

[todb-r7]

Hey @limhoff-r7 or @jlee-r7 how do I get these tests in the regular rake spec run? They're not getting picked up and I'm not sure why.

[limhoff-r7]

Only files matching spec/*_/__spec.rb will be picked up. You named the file wrong.

[kernelsmith]

Wow, even I knew that ;)

[todb-r7]

<-- noob. Thank you @limhoff-r7 ! :)

This needs to be updated now that #1444 and #1476 have been backed out, since now some methods are missing.

[limhoff-r7]

You could add :pending => '<link to PR>' to mark the examples as pending until the new PRs for 1444 and 1476 land. Or just a string saying 'Waiting for #1444 and #1476 to be remerged', but that's more opaque. Then, as part of the new PRs for that, they would remove the :pending tag, as a pending example that passes, counts as a failure since they should no longer be pending.

it 'should do something', :pending => 'reason' do
end 

Is the generic syntax.

[jlee-r7]

Dude. That's deep, man.

Thanks @jlee-r7 my notificatiosn for my own PRs are all screwed up ATM, so didn't see this (or any other comments on my PRs, boo)

[todb-r7]

Reading through @limhoff-r7 's varied pearls of wisdom, too, will implement for sure.
