[pve-devel] [RFC firewall] api: Add optional parameters `since` and `until` for timestamp filter

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

The optional unix epoch timestamps parameters `since` and `until` are introduced in order to filter
firewall logs files.

Since the `dump_logfile` function is used in multiple places, not neccessarily following the firewall
log output format, a specialized function `dump_fw_logfile` is introduced in the PVE::Tools,
with fallback to the previous `dump_logfile` function if none of the parameters is present.

This patch depends on the corresponding patch in the pve-common repository.
