Gerardo Salazar 8c6aa6a3b3 Refactors Capacity Estimation and moves estimation to main event loop (#5351)
* Adds CapacityEstimate and SymbolCapacity

  The capacity estimation has been moved from
  the report generator and wired directly into
  Lean via the ResultHandler. In addition,
  the capacity estimation strategy has changed
  to account for errors in the previous iteration
  of the capacity estimation.

  Many many thanks to Jared for being much of the
  mastermind behind this project. It would have
  been harder to complete without him to bounce ideas
  off of.

  * Moves old tests to regression algorithms
  * Adds Estimated Capacity statistic
  * Removes old capacity estimation tests

Final report capacity estimation. Pushing to save state

* Fixes bugs, cleans up code and adds comments

  * Adds forced sampling to Capacity Estimation

* Adds Capacity Estimate to all regression algorithms

* Removes Report's StrategyCapacity class and fixes bug in tests

  * Adds null check in BacktestingResultHandler to fix
    BacktestingTransactionHandler failing tests

  * Deletes old capacity estimation classes

  * Retrieve capacity estimates from backtest statistics results
    instead of calculating at runtime

* Make $0.00 capacity return as "-" and Result = 0 in report

* Adds capacity to runtime statistics

* Converts capacity to number denoted by financial figures in RuntimeStats

* Addresses review: code cleanup for Capacity and adds comments to regression tests
