Create authz authorization with limited number of uses.

[dwedul-figure]

Summary

Create an authorization for use with x/authz that restricts the authorization to a number of uses.

Problem Definition

As an asset owner, I want to give authorization to a grantee that is limited to a certain number of times, so that I can more accurately restrict the authorization.

Proposal

Create a new authorization message that has a uses left count and an underlying authorization.

MsgTypeURL should return the MsgTypeURL of the underlying authorization.
Accept should check and update the uses left and also call the Accept of the underlying authorization.
ValidateBasic should make sure the uses left is greater than zero and call the underlying authorization's ValidateBasic.

This will be similar to the SendAuthorization implementation in https://docs.cosmos.network/master/architecture/adr-030-authz-module.html#authorization except with a uses left count instead of coins, and the addition of the underlying authorization.

As part of this, we will also want to update all custom uses of authorizations (e.g. in the x/metadata module) to call the Accept method and make sure they allow for this new type of authorization (e.g. aren't limited to a generic authorization). If any such limitations exist, check for this type of authorization, and then limit off of its underlying type. In other words, don't allow this type of authorization without checking the underlying type.

Also, make sure that we can use the provenanced tx authz command stuff to add this new type of authorization.

Subtasks:

• Create a new authz authorization type that is limited to a certain number of times. #904
• Update metadata module to delete authorizations based on Delete flag. #905
