Description

Currently we explicitly set MaxPermSize in several places. Most notable - ignite.bat and ignite.sh.
As most users are on Java 8 now, they see annoying JVM warning on node startup:

OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

Let update our scripts, so that MaxPermSize is used for Java 7 and MaxMetaspaceSize for Java 8 +.
