Deprecate propose_spend dispatchable and it's dependant dispatchables, reject_proposal and approve_proposal.

The spend dispatchable is expected to be used instead.

Deprecation Issue: paritytech/polkadot-sdk#138

wonder if developers will notice these deprecations, may be there is a better way to deprecate dispatchables?
this at least will be included in release notes

You mean the pr will be included? Otherwise no one really will see this from the upper layers.

The metadata does not carry deprecation info, or?

@bkchr yes, which is a good part.
the combination of #[allow(deprecated)] and #[deprecated(...)] for one item looks hacky.
may be whitelisting those warnings could be a solution.

@ggwpez just checked, it does not. you can see it in rococo contracts, the contracts pallet has deprecated calls.
but it does include docs, so we could include it into docs.

I created a deprecation issue for it - https://github.com/paritytech/substrate/issues/14732
Can you please review the PR
I did not add anything to metadata since there is no agreement on it yet.

#[allow(deprecated)]
#[deprecated(
note = "`reject_proposal` will be removed in February 2024. Use `spend` instead."
)]

You could rename them to deprecated_reject_proposal. Then the info will be in the metadata and visible to downstream devs/users.

it can be a solution actually, but I would first agree on it and have it as a standard to not create multiple ways of deprecating

I know that "Remove usage of the deprecated feature in the code base" is listed as a separate item in the deprecation process, but I think we should already use the new syntax instead of using#[allow(deprecated)] everywhere

But we have to keep the tests in tact for as long as the code is not completely removed, otherwise it could silentlybreak.
The #[allow(deprecated)] is just for the tests here.
