Add ability to execute an Apple MDM RemoveApplication Command via fleet web ui

[jspenc72]

Problem

I want to be able to remove applications installed to iOS and iPadOS hosts via apple mdm InstallApplication commands via the fleet web ui.

What have you tried?

I am able to successfully install and remove applications on macOS hosts without issue.

I am able to successfully install applications on iOS and iPadOS hosts via the web ui but unlike macOS hosts there is no option to uninstall them in the actions drop down.

I have been able to remove applications from iOS and iPadOS hosts via fleetctl mdm run-command with the following payload .

remove-app.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN""http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
     <dict>
          <key>CommandUUID</key>
          <string>0001_RemoveApplication</string>
          <key>Command</key>
               <dict>
                    <key>RequestType</key>
                    <string>RemoveApplication</string>
                    <key>Identifier</key>
                    <string>com.example.app</string>
               </dict>
     </dict>
</plist>

fleetctl mdm run-command --payload=remove-app.xml --hosts='Test iPad'

This results in removal of the specified application if it exists on the device and if it was installed as managed.

I have not found any implementation of Apple's MDM command RemoveApplication in the fleet source code.

Potential solutions

1. Implement a RemoveApplication method in the apple_mdm.go and commander.go that dynamically populates the application identifier.
2. Add the Uninstall option to the Actions dropdown on the software page of the fleet dashboard to allow users to remove an application from iOS and iPadOS hosts.

https://myexample.fleet.host.com/hosts/2/software?order_key=name&order_direction=asc&page=0&available_for_install=true

What is the expected workflow as a result of your proposal?

1. Configure Apple Business Manager in the fleetdm settings ui
2. Purchase application licenses in the Apple Business Manager portal
3. Add the software to a team in fleetdm web ui.
4. Select a Host and install the software
5. NEW FEATURE: Select a Host with the managed application installed, open the Actions Drop Down, Click Uninstall

Should complement the workflow for MacOS and other OS's wherever possible.

Looks like this is a subset/duplicate of #20729. Keeping this open for the time being since there's a PR attached.
