fix/enhance getinfo ns/id/* commands
- Fix getinfo ns/id/* See the last few comments on #7059 (moved) with regards to the ns/id/* getinfo command.
Currently, it only returns information about tor nodes which have microdescriptors and ignores those that use "normal" descriptors, in other words, it behaves exactly like the md/id/node command.
I can understand the rationale behind having desc/id/node to only show information about tor nodes with "normal" descriptors and I can understand the reasons for md/id/node to do the same for tor nodes with microdescriptors, but ns/id/node should, in my view, be implemented in such a way to return information about all tor nodes, regardless of whether or not they use microdescriptors, particularly so because by definition of this command in control-specs.txt it is supposed to return V2 directory info on all nodes without making such distinctions.
- Enhance ns/* - just an idea (not a bug!): currently, there is no way I could get information on a tor node by specifying its ip address.
I would love to be able to get that information by executing something like "getinfo ns/ip/<ip_address>" (note the "ip" in the middle!). This should return information on all tor nodes with the specified ip address (and/or netmask), regardless of whether they use microdescriptors or not.
