Backport: cleos sorts keys/permission_levels/waits for "cleos set account permission"

[linh2931]

EOSIO/eos#10911

The keys/permissions/waits to eosio::updateauth action must be ordered. The order is not simply the string order.

At current, cleos can validate the authority data structure. But when there are multiple keys or multiple permission_levels, it is hard to figure out how to order the keys/permissions/waits. There are N! number of combinations to try for N keys/permission_levels.

It will be convenient if cleos set account permission can automatically sort the keys, permission_levels and waits for users.
