from the builds. Also remove the changelog because that file is going
to be ignored from the source tree. Ubuntu builds are being done
in the xcat-core directory and causing issues when we are switching
between releases. Should probably change the builds scripts as a longer
term solution
Cleaned up some of the comments in the beginning of buildcore.sh
using spaces instead of tabs and added the build for xCAT-confluent.
The xCAT-confluent rpm is intended to be used for xCAT2.X releases to
support confluent. This rpm has a requirement on confluent_server package.
For 2.9.1, xCAT-confluent is optional. For 2.10, the plan is to default
the console service to confluent.
