Single quotes around postfix_sasl_password in sasl_passwd file

[Salvoxia]

Hi,

the auth task wraps the postfix_sasl_password in single quotes ' when writing it to the sasl_passwd file.
https://github.com/dgibbs64/ansible-role-postfix_send_only_relay/blob/ded040dc7aa015fe0de0e9a572cb7f93e475394a/tasks/auth.yml#L62C71-L62C92

When I tried to set up postfix with this role, authentication with my SMTP relay host would always fail until I manually removed the quotes from sasl_passwd, ran postmap again and restarted saslauthd and postfix services.

Running postmap -s sasl_passwd on the host also showed the quotes around the password, so it seems they are interpreted as part of the password.

The used quote filter is used for shell quoting, so this problem will not show up if the password does not contain characters that filter would quote. If it does, quotes are added, that are interpreted by postfix literally.
