This is not necessary anymore and it prevents bigtop-utils from being used.
removing hbase-config.sh from the hbase init script is not enough.
hbase-deamon.sh also gets called and it invokes hbase-config.sh
Seems like bigtop detection of JAVA_HOME needs to happen earlier in the hbase init script.
removes the unnecessary hbase-config.sh as well as adds
bigtop-detect-javahome to the debian init scripts to be consistent with the RPMs.
