SCOPE
-------------------------------------------
Project is for running multiple tasks grouped in jobs

General workflow is:
User create job
For this job system find tasks, using AntColony and place them to general queue
Creeps (node processes) request new task
Queen (main class) find best matching task for creep using priority method as metric
Creep starting to process this task
Setup env specific for task, then check env is correct
Then it run task
Then task is completed it request new task, if queue is empty it just waiting

=============Example=======================
You need to run tests. Whole test run take,
lets say, 10 hours, but you have several boxes to run tests
Lets say you have 5 boxes and 1000 tests
You don't know (or this number is estimated) how much time
takes each test.
Before running tests you need do some setup(change branch, apply DB patches, etc)
You can split test on batches to run 200 tests in each box,
but each batch has different runtime so instead of 2 hours (10 hours / 5 nodes)
you'll get 2h 30 m (max of each batches, depending of diff between runtimes)
You can run tests one by one: each box request test to run and then it's finished
require new test. This way you can reach ~2h runtime. Lets call 
this processes - Creeps. 
For running tests one by one we need some logic to return list of tests to run
Lets call this AntColony

Now next problem. Use 5 boxes per user is very expensive. Lets share this boxes 
between all users. Different users can run different branches on same nodes.
We need to run tests as fast as possible, so changing environment (branch,db)
is expensive, and we need some logic to find "best matching test" for box
Let's call this "priority"
Also we need to keep env setup and test running logic somewhere
Lets call this 2 things CreepModifier
