Composite Run Steps Outputs (#568)

* Composite Action Run Steps

* Env Flow => Able to get env variables and overwrite current env variables => but it doesn't 'stick'

* clean up

* Clean up trace messages + add Trace debug in ActionManager

* Add debugging message

* Optimize runtime of code

* Change String to string

* Add comma to Composite

* Change JobSteps to a List, Change Register Step function name

* Add TODO, remove unn. content

* Remove unnecessary code

* Fix unit tests

* Fix env format

* Remove comment

* Remove TODO message for context

* Add verbose trace logs which are only viewable by devs

* Initial Start for FileTable stuff

* Progress towards passing FileTable or FileID or FileName

* Sort usings in Composite Action Handler

* Change 0 to location

* Update context variables in composite action yaml

* Add helpful error message for null steps

* Pass fileID to all children token of root action token

* Change confusing term context => templateContext, Eliminate _fileTable and only use ExecutionContext.FileTable + update this table when need be

* Remove unnessary FileID attribute from CompositeActionExecutionData

* Clean up file path for error message

* Remove todo

* Initial start/framework for output handling

* Outline different class vs Handler approach

* Remove InitializeScope

* Remove InitializeScope

* Fix Workflow Step Env overiding Parent Env

* First Approach for Attaching ID + Group ID to each Composite Action Step

* Add GroupID to the ActionDefinitionData

* starting foundation for handling clean up outputs step

* Pass outputs data to each composite action step to enable set-output functionality

* Create ScopeName for whole composite action.

This will enable us to add to the StepsContext[ScopeName] for the composite action which will allow us to use all these outputs in the cleanup step

* Hook up composite output step to handler => tmmrw implement composite output handler

* Add post composite action step to cleanup outputs => triggers composite output cleanup handler

* Fix Outputs Token handling start. Add individual step scope names.

* Set up Scope Name and Context Name naming system{

* Figured out how to pass Parent Execution Context to clean up step

* Figured out how to pass Parent Execution Context and scope names to
clean up step

* Add GetOutput function for StepsContext

* Generate child scope name correctly if parent scope name is null

* Simplify InitializeScope()

* Outputs are set correctly and able to get all final outputs in handler

* Parse through Action Outputs

* Fix null ScopeName + ContextName in CompositeOutputHandler

* Shift over handling of Action Outputs to output handler

* First attempt to fix null retrievals for output variables

* Basic Support for Outputs Done.

* Clean up pt.1

* Refactor outputs to avoid using Action Reference

* Clean up code

* Clean up part 2

* Add clarifying comments for the output handler

* Remove TODO

* Remove env in composite action scope

* Clean up

* Revert back

* revert back

* add back envToken

* Remove unnecessary code

* Add file length check

* Clean up

* Figure out how to handle set-env edge cases

* formatting

* fix unit tests

* Fix windows unit test syntax error

* Fix period

* Sanity check for fileTable add + remove unn. code

* revert back

* Add back line break

* Fix null errors

* Address situation if FileTable is null + add sanity check for adding file to fileTable

* add line

* Revert

* Fix unit tests to instantiate a FileTable

* Fix logic for trimming manifestfile path

* Add null check

* Revert

* Revert

* revert

* spacing

* Add filetable to testing file, remove ? since we know filetable should never be non null

* Fix Throw logic

* Clarify template outputs token

* Add another type support for outputs to avoid container unit tests errors

* Add mapping for parity

* Build support for new outputs format

* Refactor to avoid duplication of action yaml for workflow yaml

* Move SDK work in ActionManifestManager, Condense Code

* Defer runs evaluation till after for loop to ensure order doesn't matter

* Fix logic error in setting scope and context names

* Add Regex + Add Child Context name null resolution

* move private function to bottom of class
