[pve-devel] [PATCH common] tools: template_replace: esacpe braces

[Thomas Lamprecht]

To avoid warnings (and in the future, errors) like:

> Unescaped left brace in regex is deprecated here (and will be fatal
> in Perl 5.32), passed through in regex; marked by <-- HERE in
> m/([^{]+)?({ <-- HERE ([^}]+)})?/ at /usr/share/perl5/PVE/Tools.pm
> line 673.

with future perl versions, like Debian Buster for example has.
