Add user ID to VmInfo and display in clients
This commit adds user ID information to the VmInfo Pojo, which is
gathered by SystemBackend. The UID for a VM is collected by parsing
/proc/${pid}/status, and we then get the username for the UID from the
native function getpwuid_r. Both the vm-info command and the VM Overview
tab of the Swing GUI now show the user under Process Information. I took
inspiration from the id Unix program for the formatting, which is
"uid(username)". The native component of this commit is added to
agent-core for use by system-backend, this was done on request by Mario
since agent-core already has a native component for getting the
hostname. I made this component an OSGi service primarily to hide its
implementation details.
