Full support for WireMock options

[hprange]

Developers can configure the WireMock Java library in many ways to fulfill their testing requirements. The clj-wiremock wrapper, in contrast, only allows the HTTP port to be configured. This pull request adds support for all WireMock options (as of version 2.27.2).

A few considerations about this change:

• It's one of my first projects using Clojure. Please, let me know if there's a more idiomatic or straightforward way to implement it. I'll gladly amend the pull request.
• I haven't tested custom certificate options because it requires valid certificates. If you think it's worth it, I can create fake certificates, add them to a test-resource folder and write the test cases.

@kelveden any comments on this pull request? Any chance to get it merged? Do you want me to make modifications before you accept it? We use Wiremock extensively in our company, and it would be great to change options in a more idiomatic way. Thanks!
