Added SCMB module and CLI command

[jsmartt]

Description

Adds a module that makes it easy to connect to the OV SCMB. This does add a dependency on an additional gem, bunny. There's only 1 other dependency in the chain, so it adds 2 total gems to the run-time dependencies.

Side note: I also updated the CHANGELOG headings to be consistent: # for major releases, ## for all other releases, and #### for sub-sections in releases.

Note: I'm getting a OpenSSL::X509::CertificateError (not enough data) error when I run the CLI on Windows, because of this issue. Windows users can get around this by adding in the :tls_ca_certificates option when creating a connection, but I'd like to avoid Windows users having to be explicit about it. Let's hold up on this PR until we get a reply on that issue.

Update: I got the change merged in to bunny to fix Windows clients. We're still waiting on a release, but I think it's fine to move on with this PR now; when bunny gets released (2.6.5), it'll fix the issues for Windows. Can someone take a look at this PR and validate it working in your (Linux) environment?

@jsmartt

Yeah! I Can. Wait a bit please.

[aalexmonteiro]

Looks good for me! I tested and works fine.

[jsmartt]

Now that bunny 2.6.5 is out, I think this is ready to be merged in. Any reservations @tmiotto or @fgbulsoni?

Missing link for an issue related? Also, since this is something new, maybe add it under new resource/new feature instead of enhancements and bug fixes?

[jsmartt]

@fgbulsoni, I added the change under a "New Features" section, but there's no issue to attach it to, so still no link.
