Generator dummy database
Related issue: #521
Currently the lava_db_generator python module is a part of lava-server debian package. It should probably be moved to lava-dev debian package?
The lava_db_generator module provides two commands: generatedb and runsimulation
generatedb can either generate a specific entity like TestJob with parameters or a specific set of entities under a scenario. For example, there is a scenario for testing scheduler scheduler_test which generates test jobs that have specific health set to be schedulable.
runsimulation runs a specific set of commands that can test performance. Currently there is only one simulation: scheduler. It runs the scheduler code to schedule all the test jobs eligible. This can be used to test scheduler performance. The simulation also patches some of the calls that can affect the state of the system.
Extra generators, scenarios and simulations can be added in the future.
