Add undeploy_first parameter to wildfly_deployment

[alexjfisher]

Instead of using cli.update_deploy, when setting this parameter to
true, the deployment is undeployed, before being redeployed.

TBH, I'm disappointed I couldn't figure out any way to avoid writing this change.

I played around with

operation-headers => { 'allow-resource-service-restart' => true }

but for some reason, when updating my ear, I'd still either have to manually undeploy it first, or restart the whole wildfly server.

Naming things is hard! undeploy_first was the best I came up with. Open to suggestions. :)

Completely unrelated, but now the desc matches the defaultto below.

Acceptance test failures appear unrelated.

@biemond Build is still failing due to an issue downloading Oracle java in the beaker tests. Is this something that you have to fix up on a regular basis?
