[pdm-devel] [PATCH datacenter-manager 4/6] ui: resource tree: use an async pool for requests

[Shannon Sterz <s.sterz@proxmox.com>]

the async pool will abort the requests it is managing when the
component is dropped. this avoids a potential race condition between
these requests and a log in attempted right after a log out.
