Feature Description

My idea is to

• add a Ephemeral field to the database structure of the Runner
• when the Ephemeral field is true let FetchTask return no task without error if the assigned task is in progress
• when the Ephemeral field is true let FetchTask return no task with an error if the assigned task is in done, and remove the runner from the database.
• UpdateTask and UpdateLog scope access to runnerid (Done)
• Update the runnerv1 protocol to have an Ephemeral field as well during registration
• Update act_runner to have the ephemeral flag, which implies run-once

This proposal would allow to securely deploy a registred host-mode act_runner in a VM and reset the same after job exit.

Some of my idea has been scetched in https://github.com/ChristopherHX/gitea/tree/ephemeral-runners.
