Use human friendly names in task names and notifications for Tower CUD operations

[jameswnl]

A further improvement on top of #14656 for https://bugzilla.redhat.com/show_bug.cgi?id=1439203
and for https://bugzilla.redhat.com/show_bug.cgi?id=1448081 as well.

Use human friendly names instead of the class names in task names and keep the notification message brief and user friendly.

Before:

e.g.

• User would see in task:Creating ManageIQ::Providers::AnsibleTower::AutomationManager::ConfigurationScriptSource name=My repo
• User would see in notification: The operation ConfigurationScriptSource update_in_provider {:name=>..... create_on.....} completed successully

Now:

e.g.

• User would see: Creating Ansible Tower Project (name=My repo)
• User would see in notification: The operation Ansible Tower Project update (name=My Repo, manager_ref=1) on Tower(manager_id=10000000) completed successfully.
• The detail parameter hash (sans secrete) would be logged into logs
