The rsyslog role has served us well however there's now a better way
given the ability to remotely journal. This change disables the use of
the `rsyslog_client` and `server` roles unless journal remote is
unavailable. In this change the `rsyslog_client` interaction has been
moved into an include_tasks which is conditionally loaded when the
variable `rsyslog_client_enabled` is set to true. Additionally the
`rsyslog_server` role is disabled unless `rsyslog_server_enabled`
is set true. Using the new variables legacy functionality can be
enabled. By disabling the general rsyslog roles we'll lessen the
overall IO on the cloud and improve the speed of the deployment.
> NOTE: At this time there's no suitable package to install
"systemd-journal-remote" on opensuse so a conditional has been
added to ensure distributed log syncing remains functional on
all of our supported distros. Should a package be made
available for journal remote we can globally disable the
legacy rsyslog roles entirely by default.
