Statemine v504 (Polkadot v0.9.11)

This release upgrades Statemine and Westmint to Polkadot v0.9.11 and introduces transaction payment in assets.

❗️Important Changes

• Support for Asset Transaction Payment (#488)
  • This changes the transaction format by swapping out a SignedExtension which leads to a transaction_version bump to 3.

Notable Changes

• Metadata v14: paritytech/substrate#8615
• Make Parachain sync protocol future proof: #640
• Fix state_subscribeRuntimeVersion for Parachains: paritytech/substrate#9617
• Improve performance for Parachains when building blocks: paritytech/substrate#9611
• • Transaction priority calculation was changed to be based on the tip to weight/length ratio (#645)
  • see paritytech/substrate#9834 for details
• Add Transaction Fee RPC to Statemint/Statemine (#559)
  • Note that this does not support asset transaction fees, yet.
• Support for Reserve Asset Transfers via XCM (#552)
• Support for XCM v2 (#571) (see paritytech/polkadot#3629 for details)

Other Notes

• The spec_version convention was changed from single digits to hundreds (so v5 is spec_version 5xx now)
• The spec_version 5 runtime live at time of release is the hotpatch to runtime version 4 (you could think of it as 401 in the new format).
