Commit c72910a8bf782c10662dd4392e81ef6408f801ee

Authored by Felix Gilcher

Exists in master and in 4 other branches 6-8-stable, 7-0-stable, 7-0-stable-spb, spb-stable

log fatal errors that we catch 

In case we rescue from a fatal error, we want the error and the backtrace to
the error logged, so we can debug later on. This change injects the configured
logger from the rails app to the grape API and logs error as well as backtrace
in a rails-like fashion.
