Change Command Argument to multiple arguments (#6520)

file.sh(see next lines) shows how arguments are passed to the pod
#!/bin/bash
while :
do
  echo arg1 = $1 arg2 = $2
  sleep 10
done

In UI create form the following entries are made
Run command: ./file.sh
Run command arguments: argument1 argument2 argument3

Before change:
POD log shows
arg1 = argument1 argument2 argument3 arg2 =

so all 3 arguments are passed as one argument

Deployment yaml shows(only container part)
    spec:
      containers:
        - name: demo-arg-old
          image: tcnthomas/arguments
          command:
            - ./file.sh
          args:
            - argument1 argument2 argument3

After change
POD log shows
arg1 = argument1 arg2 = argument2
First 2 arguments are shown as expected.
3rd argument is not shown as it is not part of the script

Deployment yaml shows(only container part)
    spec:
      containers:
        - name: demo-arg-new
          image: tcnthomas/arguments
          command:
            - ./file.sh
          args:
            - argument1
            - argument2
            - argument3
