tc Server must be ran as root

Because GemFire tries to access the file "/vf.gf.dmn-license.cfg" tc Server must be ran as root, which is not recommended.

The exception generated if tc Server is ran under the tcserver user is:

Caused by: com.gemstone.gemfire.LicenseException: Failed to access/create local file /vf.gf.dmn-license.cfg: java.io.IOException: Permission denied
