TLS support in syslog package

[cancan101]

Currently the syslog packages does not work with a syslog log destination with TLS support.

See: moby/moby#18358

We have no plans to further develop the log/syslog package in the standard library.

We welcome the community to fork it and give it features elsewhere. It was probably a mistake putting it in the standard library to begin with.

If anyone is looking for syslog with TLS, we've forked the original library and added TLS support here:
