Only include ssl bits when ssl is enabled

[jyaworski]

Hello:

I noticed that when ssl isn't enabled, that running rd-jobs from the cli produces ssl warnings:

[root@rundeck rundeck]# rd-jobs list -p Infrastructure
Error: Error making server request to http://rundeck:4440: Error occurred while trying to authenticate to server: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

This PR only calls the SSL bits when it's enabled.

This works, but the test fails because I'm no longer including the class. I'm open to ideas on how to fix this; I'm not great with tests.

We could do this a little better by switching to an alternative syntax e.g.

include 'rundeck::config::global::framework'
...

if $ssl_enabled {
   include 'rundeck::config::global::ssl'

   Class['rundeck::config::global::framework'] ->
   Class['rundeck::config::global::rundeck_config'] ->
   ....
   Class['rundeck::config::global::ssl']
} else {
  Class['rundeck::config::global::framework'] ->
   ...
  Class[''rundeck::config::global::rundeck_config']
}

...

@liamjbennett this is finally ready to merge.
