Daemon selection for ExApp installation

[andrey18106]

Describe why it is important and where it will be useful

It would be useful to be able to select on which daemon to install ExApp, not only to default one.

Describe your proposed solution

Add option in the UI to select on which daemon (or daemons cluster) to install ExApp.

Describe alternatives you've considered, if relevant

No response

Additional context

Also this might be relevant and required in case of scaled ExApps to be able to install ExApp on multiple daemons, but this requires more advanced daemons configuration (groups or clusters of daemons) and possibility to select on which group of daemons to setup ExApps.

Explanation:

The external applications page is located by clicking "menu->External applications"

After that, you need to go to the "Tools" category

When you click the "Deploy and enable" button, a menu appears for selecting a deployment daemon (if there is more than one deployment daemon on the instance)

Backend endpoint need small adjustments with adding a parameter that receives the daemon_id for the installation.
