plugin/sign: a plugin that signs zone (#2993)
* plugin/sign: a plugin that signs zones

Sign is a plugin that signs zone data (on disk). The README.md details
what exactly happens to should be accurate related to the code.

Signs are signed with a CSK, resigning and first time signing is all
handled by *sign* plugin.

Logging with a test zone looks something like this:

~~~ txt
[INFO] plugin/sign: Signing "miek.nl." because open plugin/sign/testdata/db.miek.nl.signed: no such file or directory
[INFO] plugin/sign: Signed "miek.nl." with key tags "59725" in 11.670985ms, saved in "plugin/sign/testdata/db.miek.nl.signed". Next: 2019-07-20T15:49:06.560Z
