ignite-hadoop service doesn't start

In BIGTOP-2097 some cleanups and improvements of the ignite packaging has been done. Unfortunately, now the service can not be started.

1. the startup script is still called ignite-hadoop and as the result {[service ignite-hadoop-service start}} fails.
2. the way the service script is generated, is toload a default file with the same name from /etc/default. However, right now default file is still at ignite-hadoop, but even if 1. above is fixed, it won't be able to load the faults and will fail.

Alleged, the same will be happening on RPM side.

Clearly, this mess needs to be fixed.
