jython script to add Generic JVM arguments for Log4j Security Vulnerabilities fix

$ ./wsadmin.sh -lang jython -f addJVMArg_new.py server1 add "-Dlog4j2_formatMsgNoLookups=true"
WASX7209I: Connected to process "server1" on node AppNode01 using SOAP connector;  The type of process is: UnManagedProcess
WASX7303I: The following options are passed to the scripting environment and are available as arguments that are stored in the argv variable: "[server1, add, -Dlog4j2_formatMsgNoLookups=true]"
JVM Name is :  server1
Action is :  add
JVM ID is (cells/Cell01/nodes/AppNode01/servers/server1|server.xml#JavaVirtualMachine_1183122130078)
JVM Arguments are : -Xcomp -XX:-TieredCompilation
new_argument is :  -Dlog4j2_formatMsgNoLookups=true
-Xcomp -XX:-TieredCompilation
Need to add the arguments
modified arguments is as below :
-Xcomp -XX:-TieredCompilation -Dlog4j2_formatMsgNoLookups=true
