In a distributed setup, the Test agent connection slide-in offers a download command for the host-specific agent. So far this download only worked for hosts that were already activated on their monitoring site -- for hosts that were just created and pinned to a remote site, the download from the remote site failed.
With this change, the remote site fetches the host- or folder-specific agent package on demand from the central site and delivers it to the host. The user can install and register the agent before activating changes, which keeps the host out of monitoring until everything is ready. The proxied download endpoint on the remote site now offers the same coverage as on the central site (per host, per folder, vanilla).
The remote site authenticates against the central site with the distributed-setup site secret that is already established when the remote site is registered. The URL of the central site has to be configured under Global settings → Automatic agent updates → Connection to central Agent Bakery. If the setting is not configured on the remote site, the slide-in download responds with a clear hint to configure it, instead of a generic error.
