Description

On Centos 8 the package snappy-devel lives in the PowerTools repo, which is not enabled by default; so bootstrap_system.sh installs it by enabling the repo using a command-line argument passed to dnf (the Centos 8 package manager).
Centos 8.3 changed the capitalization of repo names: earlier names used MixedCase, while 8.3 changed to repo IDs in all lowercase. Unfortunately this causes the dnf install call to fail with an "unknown repo" error.
This breaks Docker-based tests for Centos 8, which is currently the only way to run Impala tests on that platform.
