Importing agl-service-taskmanager code

The service queries /proc for system statistics data and
collects data for all processes currently running
on the system. The data for each consists of process name,
process ID, user, system CPU usage, user CPU usage, memory and state.
The data is then converted to JSON and sent to the requesting app.

v1
 - removed trailing whitespaces
 - added description in the README file
 - removed URL from config.cmake

v2
 - added project URL to config.cmake
