Opening URLs through automate

[martinpovolny]

RFE BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1550002

Requires:

• Support for opening URL from the UI through automate. manageiq#18849 (merged)
• Support for opening URL from the UI through automate. manageiq-automation_engine#328 (merged)
• Open URL through automate for various objects manageiq-schema#380 (merged)

Doc PR: ManageIQ/guides#355

TODO

• specs (existing specs are updated, but more tests would be good, will do that in a follow-up PR)
• pass the targetClass though the form, (needs to be checked)
• allow the OpenURL checkbox when editing custom buttons for all relevant classes.
• update the documentation (from here: Fix open_url with dialog #4334) and put it to guides

Tested automate code for User

$evm.log(:info, "Current user_id #{$evm.root['user_id']}")
object = $evm.vmdb($evm.root['vmdb_object_type']).find_by(:id => $evm.root['user_id'])
$evm.log(:info, "Current object #{object}")
object.external_url = "https://www.linkedin.com"

(the vmdb_object_type would work for other entities as well, but the ID is stored elsewhere)

Tested automate code for VM

vm = $evm.root['vm']
$evm.log(:info, "VM to launch SSH for is #{vm.hostnames[0]}")
vm.external_url = "https://www.redhat.com"

A screenshot to help navigate in the UI

(it's best to follow the Guides article in the above PR)
