Martin Molinero 4382aa1886 Add algorithm thread 
- Adding `WorkerThread` class, wrapper for a worker thread that will
execute given `Actions`.
    - Algorithm related code (`Construction`, `Initialization`,
    `Execution` will be executed by the same `WorkerThread` instance,
    this is required for `Python` debugging.

Stefano Raggi 462ca4ecab Add total application memory usage in Isolator logging 
- Added logging of total memory usage, which includes both managed and unmanaged memory
- Fixed incorrect calculation of total physical memory for Windows

Martin Molinero 4d7dfe1c89 Initialize algorithm faster 
- ISetupHandler implementations will now use 50ms as sleep interval
while initializing the algorithm
- If the sleep interval is >= to 1s (default value) it will divide the
sleep operations into 5

Martin Molinero 8ac4b37e5f Load algorithm faster 
- Make `Isolator.ExecuteWithTimeLimit()` sleep interval configurable.
- `Loader` will now use 50ms

Michael Handschuh 818591e101 Revert "Isolator will now take into account unmanaged memory usage" 
This reverts commit 221a90c81a.

Causing algorithms to fail. This wasn't intended to be merged until
after the pythonnet memory leak fix has been merged/deployed.
