Gradle task that reports if Tomcat, HSQL is running

[bjagg]

Is your feature request related to a problem? Please describe.
Sometimes we forget if Tomcat or HSQL are running. Other times Tomcat does not stop after running ./gradlew tomcatStop.

Describe the solution you'd like
Given the start and stop tasks for Tomcat and HSQL, I would like a two new tasks that report if those services are currently running.

Describe alternatives you've considered
Currently, I run pgrep -f tomcat and pgrep -f hsql to check if they are running. This does not work on Windows, however.

I know that there's a check for HSQL as I've forgotten on occasion. It's implemented at https://github.com/Jasig/uPortal-start/blob/master/gradle/tasks/hsql.gradle#L20

Awesome! The we just need to rename it, add a description, then make it public.
