Processors that use `invoke` package to make chain invocation should provide fee config and client with enabled or disabled notary support. If notary support is disabled, then functions from `invoke` package will perform ordinary method invocation with extra fee. Processors that use `morph/client` wrappers should check `notaryDisabled` flag to call corresponding wrapper function. Netmap processor omits some actions during validator syncronization if notary is disabled. Signed-off-by: Alex Vanin <alexey@nspcc.ru>
