Wildcard permissions support #439
Description
Is your feature request related to a problem? Please describe.
As of #438 it is now possible to create custom macaroons with permission to access specific URIs. However, there are hundreds of possible URIs available in lnrpc, looprpc, poolrpc, and frdrpc.
Describe the solution you'd like
It may be useful in some situations to allow wildcard permissions, for example, to allow access to all of the URIs in poolrpc while still enforcing more granular control over lnrpc.
