Adalyat Nazirov a4f66628fd Lean Optimization interface in QCAlgorithm (#4923)
* initial commit

* run parametrized algorithm with command line parameters

* skeleton: top level structure

* OptimizationNodePacket scheme

* pass parameters as HashSet

* run Lean and read results

* call method on optimization completion

* refactor public interfaces

- close ParameterSet collection; allow only get operations
- explicit method to start LeanOptimizer

* synchronize RunLean method; the result could come in before the backtest id is set in the collections

* another portion of refactoring and interface changes

* comments

* comments & tests for Extremum, Minimization and Maximization classes

* unify optimization paramater values (min, max, step) & mode GridSearch tests

- swap min&max if necessary
- iterate left => right (negate step value if necessary) & provide default step value if step == 0
- no StackOverflow Exception
- parameterSet Id should be global for current generator and retain between steps
- test signle point boundary (min == max)

* BruteForceStrategy tests

* more comments

* Update Optimizer assembly information

- Update Optimizer projects assembly information to match behavior of
  the other projects

* Tweaks

- Adding comments
- Replace OnComplete for Ended event
- Replace Abort for Dispose
- ConsoleLeanOptimizer will keep track of running processes
- Each backtest will store results in a separated directory, so they
  don't fight for the log.txt file.
- Adding cmdline option for lean to close automatically
- Adding concurrent execution backtest limit
- Console optimizer will start Lean minimized
- Escape spaces in Json path

* remove parameter set generator abstraction layer

we don't need this flexibility now.

* refactor public methods; Step shouldn't be public

* constraints: wip

* define contract

* comparison operators and tests

* specify JsonProperty values

* Move SafeMultiply100 to extensions

* Throw exception on failed Optimizer.Start

* constraints: wip

* change finish & dispose process

* minor fixes

- handle force lean abort
- notify consumer if target has been reached

* target & constraints; adapt unit tests

* Minor Tweaks and fixes

- Some logging improvements
- Remove Public since not required

* Ignore empty ParameterValue

* simplify condition

* avoid reinitialization

* reduce type; force immutable

* unit tests for constraints  and target value

* parse & normalize percent values, i.e. 20% => 0.2

* fixup

* Target & Constraint & OptimizationNodePacket unit tests

* Add more json unit tests

- Adding more json conversion unit tests. Fix bug for Extremum which
  wasn't using the converter.

* LeanOptimizer tests

* Estimation results

* User thread safe counters

* LeanOptimizer unit tests; push OptimizationResult on Ended event

* more unit tests

* Minor tweaks

-Estimate ToString in a single line.
-Typos and missing header file

* Add base SendUpdate method

- Add base SendUpdate method for LeanOptimizer

* fix LeanOptimizer test; rely on internal Update rather than timer

* Add OptimizationStatus

- Add missing commments and OptimizationStatus

* EulerSearch implementation: wip

* OptimizationParameter custom converter

* change the type

* make step optional

* change folder structure

* enumerate optimization parameter using IEnumerable & IEnumerator

* unit tests: parameters & objectives

* unit tests: strategies

* remove redundant TODO

* change Euler search boundaries

* more Euler tests

* prevent race condition

* Add account/read endpoint

- Adding account/read endpoint. Adding unit test

* Add status check before running lean

* Minor self review

- Adding missing comments, minor changes

* remove array parameters

* minor changes

- tidy up config file, rename variable
- accept min less or equal than max

* move OptimizationParameter methods to strategies

* Minor improvements for BaseResultHandler derivates

* minor changes

- strict requirements for Step and MinStep values
- strategy specific settigs

* Add TotalRuntime to estimate
