When printing out a stacktrace with a logged error message, it is better
to set the `Stack` property on the entry than to include it as a string
within the context fields. It is also better than using `zap.Stack()`
too.
This is because certain encoders will perform a pretty print of the
stacktrace. The default zap-logfmt will read this property and include
it as a field so this code is identical when using that encoder, but the
console encoder, which is commonly used in local development because it
is automatically used with a TTY available, will print out a newline and
pretty print the stacktrace if it is included on the entry itself.
We are moving the necessary code for 2.0 from the influxdb 1.X
repository to the platform 2.0 repository. The logger is an unnecessary
dependency on the old influxdb that is making life more complicated.
