[PATCH manager 0/3] add opt-in IPMI SEL log tab for nodes

[Luca Vornheder <luca@vornheder.cloud>]

This series adds a per-node, opt-in view of the IPMI System Event Log
(SEL) to the GUI, as requested in
https://bugzilla.proxmox.com/show_bug.cgi?id=7656.

A new 'IPMI' tab next to the system log of a node lists the entries of
the SEL of the node's local BMC, read in-band via 'ipmitool sel elist',
with reload and export buttons. The feature is off by default and is
enabled per node through a new 'ipmi-sel' node option, either in the
node's options in the GUI or with 'pvenode config set --ipmi-sel 1'.
While it is disabled, the API returns 501 and the tab shows a hint
instead of an error.

Design notes / open questions:

* Only the local BMC of the node itself is supported (no remote,
  out-of-band access with stored BMC credentials).
* The endpoint uses the existing Sys.Syslog privilege, like the other
  log endpoints. Enabling the option needs Sys.Modify, as for all node
  options.
* 'ipmitool' is only a Recommends of pve-manager, as the feature is
  opt-in. The GUI marks the feature as technology preview.
* Only reading the log is implemented, there is no way to clear it.
* I did not add documentation to pve-docs yet, I'm happy to do that in
  a follow-up once the general approach is fine.

Tested on a PVE 9.2 node: option toggling in the GUI and via pvenode,
the disabled/enabled behaviour of the tab, and the export. 'make check'
passes, apart from test-ceph-key-migration (2 failing sub-tests in
CephKeyMigrationScript_test.pl), which fails the same way on an
unmodified master and is unrelated to this series.
