A0-1502: Finality version e2e test (#717)

* Setting up AlephBFT version

* Changed handling to map from session to version

* Changed logic to handle serving last set AlephBFT version

* Changed logic to handle setting of version in future only

* Reworked storage and accessors to only store one version plus session to change it

* Treat version change as a delimiting flag

* Loose coupling between pallet_aleph and pallet_session to access current session index

* Fixed trait implementation for mock

* Added comment to trait

* Replaced panics with Results in AlephBFT version handling

* Changed logic to work with numbered versions

* Changed behavior on session start and end

* Fixed version change update

* Linked SessionManager in runtime

* Mock impl

* Reworked SessionManage link

* Linter

* Removed pallet_elections from mock

* Removed event

* linter

* Linter

* Reworked AlephBFT version history updates

* Reworked storage to use value instead of map

* Added unit test

* Added version change unscheduling and next session version

* Removed explicit version unscheduling; added version default

* Extended docs for pallet aleph

* Moved default AlephBFT version to const

* Renamed helper function

* Fixed test

* Changed naming

* Bumped spec version

* Bumped transaction version

* Finality version RPC and e2e test, first stab

* Added GenesisBuild to pallet_aleph

* Added finality version e2e test

* Reworked test logic

* Removed unused imports

* Dependency version fixes; prep work for test logic change

* Post factum checks

* Changed checks; changed finality version update session

* Added test description

* aleph-client and aleph-e2e-client version bumps

* spec_version and transaction_version bumps

* Changed comment about error code

* Added doc comment

* Cargo.lock

* Bumped runtime version

* Disabled runtime upgrade check in CI

* Revert "Disabled runtime upgrade check in CI"

This reverts commit e4cc57b.

* Disabled runtime upgrade check without removing it

* Post-merge cleanup

* Back to storage; handle connection refactor

* Codegen

* Bumped aleph-client version

* Back to rpc call; prelims

* Rpc interface

* Rpc

* Link with node

* Rpc request; cleanup

* Partial fix

* Fixed RPC params

* Versioning

* Linter

* Default version fix

* E2e test version bump

* Interface reorg

* Linter

* Connection fixes; pipelines

* Linter

* Finality version set in chain spec

* Subxt codegen

* E2e test fix

* Runtime metadata for aleph-client

* Hide doc warnings

* Removed hide docs

* Actually check the version change

* Subxt metadata

* Linter cleanup

* Const reorg

* Current finality version calculated based on the legacy one
