Remove Executed Migrations (#7495)
* Polkadot is at .42 Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Kusama is on .43 Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Westend is at .43 Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Rococo is at .42 Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Make UMP limits migration more idempotentish Already 100% idempotent per design, but not it wont try to schedule an unneeded upgrade. Note that the case that the new upgrade is already scheduled is not checked. In that case it will still upgrade the same thing again, but should be no problem. Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Clippy Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Delete old migration code Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * fmt Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Remove old tests Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Polkadot is at .43 Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Remove a ton of shit Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Remove more Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Remove unused code Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Rococo is NOT yet at .43, but remove anyway Rococo is the only runtime that is not yet at .43, but keeping the migration code just for it is not worth it since devops can just apply it at any time. Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Remove old test Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> --------- Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: parity-processbot <>
