[PATCH proxmox-backup 2/2] api: h2service: avoid logging heartbeat requests to task log

[Christian Ebner <c.ebner@proxmox.com>]

Heartbeat requests can happen with a frequency as high as 1/s, adding
individual lines to the task log.

Use the http2 service filter function to exclude these request from
being logged by matching method and path accordingly.
