[pbs-devel] [PATCH proxmox-backup 2/2] acme: plugin: add sleep for dns propagation

[Stoiko Ivanov <s.ivanov@proxmox.com>]

the dns plugin config allow for a specified amount of time to wait for
the TXT record to be set and propagated through DNS.

This patch adds a sleep for this amount of time.
The log message was taken from the perl implementation in proxmox-acme
for consistency.

Tested with the powerdns plugin in my test setup.
