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
  * Misc. bug fixes for daily data

* Updates capacity test cases' Estimated Strategy Capacity statistic

* 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

Colton Sellers 43a540cbb1 OpenInterest Bug Fixes (#5207)
* Filter values that are before subscription start time; also adjust starttime for OpenInterest

* Use data EndTime for comparison

* Allow Auxiliary data through

* Fix OpenInterest DataReader Logic

* Add regression

* Address review

* Ignore open interest for time slice

- TimeSliceFactory will directly ignore open interest for determining if
  the slice has data or not. Open interest will still be available
  through the Tick collection. Reverting some of the previous commits
  changes since they are no longer required.
- HistoryRequests and SubscriptionRequest will use AlwaysOpen exchange
  for open interest requests. Adding unit test reproducing issue
- Adding `BaseDataRequest` to avoid duplication logic.

* Make OpenInterest an internal feed and ignored by default in history

- Adding unit tests

* Revert SubscriptionFilterEnumerator Start time addition
