- Use logger for all warnings. Previously we were writing warnings from
cmd/server.go directly to stderr which bypassed our normal log format.
- Add the timezone to log output. This is just really nice to have if
you're looking at old logs.
- Change levels to all be 4 characters: DBUG, INFO, WARN, EROR. This
makes the logs easier to read because it lines up.
- Log when we first receive the request as well as when we send a
response. This makes it easier to see where the request starts and ends.
Previously, we were just logging when an error happened early in our
comment processing code. However it's possible for us to write comments
on error even at this early stage which will make for a better user
experience.
Fixes#398
* If output is longer than 12 lines, wrap it in markdown folding for
GitLab and GitHub.
* Reformat the Terraform plan output so that the + and - lines show up
highlighted properly when using the diff syntax highlighting
