Feature request: Manage (enable/disable) aliases from web ui

[cognifloyd]

It would be nice to be able to see and enable or disable aliases from the web ui.

This would probably need its own dashboard (like actions, rules, triggers, etc).

The aliases are available via https://api.stackstorm.com/api/v1/actionalias The CLI uses the actionalias endpoint for these:

• st2 action-alias list
• st2 action-alias get <ref-or-id>
• st2 action-alias update <name-or-id> <file> (we would need to use this PUT endpoint to enable/disable)
• st2 action-alias delete <name-or-id>
• st2 action-alias create <file> (maybe we could have a + for adding aliases like we have for workflows)
• st2 action-alias match <command> (testing alias matching would be cool from the webui)
• st2 action-alias execute <command> (probably would want to hold off on this one from the webui)
