>> This PR is to fix the formatting issue of the JVM PID on JVM information screen. JVM PID attribute is received as NUMBER from JFR and hence the JMC application is treating is as number. When the number is smaller , the PID is displayed using commas and when the number is larger, its converted to exponential format. This is a long pending bug in product.

So in order to maintain consistency, we have made the content type of PID attribute of JVM Information event also as String. We are converting the number value of PID to string and then storing it.
