The purpose of this referendum is to perform a runtime upgrade on Pendulum. The changes included are:

- Setting up the `fee_per_second` parameter to calculate and apply fees appropriately when assets are transferred.

For more details, please refer to the [GitHub release page](https://github.com/pendulum-chain/pendulum/releases/tag/pendulum-release-16).

Schedule the currently externally-proposed majority-carries referendum to be tabled
immediately. If there is no externally-proposed referendum currently, or if there is one
but it is not a majority-carries referendum then it fails.

The dispatch of this call must be `FastTrackOrigin`.

- `proposal_hash`: The hash of the current external proposal.
- `voting_period`: The period that is allowed for voting on this proposal. Increased to
	Must be always greater than zero.
	For `FastTrackOrigin` must be equal or greater than `FastTrackVotingPeriod`.
- `delay`: The number of block after voting has ended in approval and this should be
  enacted. This doesn't have a minimum amount.

Emits `Started`.

Weight: `O(1)`

Authorize an upgrade to a given `code_hash` for the runtime. The runtime can be supplied
later.

The `check_version` parameter sets a boolean flag for whether or not the runtime's spec
version and name should be verified on upgrade. Since the authorization only has a hash,
it cannot actually perform the verification.

This call requires Root origin.
