* HoldReason: Improve usage
`HoldReason` was switched recently to use the `composite_enum` attribute that will merge the enums
from all pallets in the runtime to `RuntimeHoldReason`. `pallet-nis` was still requiring that the
variant was passed as constant to call `hold`. The proper implementation is to use the `HoldReason`
from inside the pallet directly when calling `hold`. This is done by adding a `RuntimeHoldReason` as
type to the `Config` trait and requiring that `Currency` is using the same reason. Besides that the
pr changes the name `HoldIdentifier` in `pallet_balances::Config` to `RuntimeHoldReason`.
