* Add quiet flags to package manager invocations
Add the following flags when 'certbot-auto --quiet' is invoked:
- Add '-qq' to calls to 'apt-get' in Debian
- Add '--quiet' to calls to 'yum' or 'dnf' in CentOS or Fedora
- Add '--quiet' to calls to 'urpmi' in Mageia
- Add '--quiet' to calls to 'pkg install' in FreeBSD
* Fix $QUIET flag in bootstrappers
- Set the value of $QUIET properly (i.e. s/$QUIET/QUIET when setting the
variable) in
- deb_common.sh
- mageia_common.sh
- rpm_common.sh
- Actually use $QUIET when running $tool in rpm_common.sh
* Add handling of $QUIET to Arch and Open Suse
* Add logic to set --non-interactive if --quiet
* Add missing $QUIET_FLAG to rpm_common.sh
* Run build.py
* Limit --help to 80 cols
* Update indentation within bootstrappers
* Add $QUIET_FLAG to second call to `urpmi` (redux)
* Make certbot-auto indentation consistent
Since a majority of certbot-auto uses 2 spaces per indentation level,
made indentation in letsencrypt-auto and platform-specific shell scripts
a consistent 2 spaces
Fixes#3902
* Fix last `if` statement body in rpm_common.sh
* Add better error handling for invalid FQDNs
Add explicit error handling for labels that are empty. Also add test
cases to test invalid domains.
* Add more thorough tests
