[RFC common/cluster v4 0/5] cluster files: support registering UTF-8 configuration file

[Fiona Ebner <f.ebner@proxmox.com>]

Changes in v4:
* rather than searching for wide characters, tell parse_config()
  directly whether the file was registered as UTF-8

Changes in v3:
* rebase on current master.
* add patch to use strict UTF-8 encoding when writing.
* use strict UTF-8 for {de,en}coding in the rest of the series.
* let cfs_register_file() take an $options parameter rather than
  an $utf8 parameter, so future call sites are more readable.

Changes in v2:
* rebase on current master.
* use qw(encode) when importing Encode module.

A configuration file registered as UTF-8 will be automatically decoded
from UTF-8 to Perl's internal string format after reading and encoded
in the other direction before writing.

Patch 1/5 also makes sense without the rest of the RFC.

Note that patch 4/5 (required by 3/5) is a versioned breaks for
libpve-access-control which still needs to be bumped! Could be avoided
by keeping the implicit return of cfs_register_file(), but that's bad
for encapsulation.

Versioned dependency bump pve-cluster -> pve-common needed!
