This change adds a trusted registry (via the source code) of node address to node id mappings (currently only for well known Satellites) to defeat MITM attacks to Satellites. It also extends the uplink UI such that when entering a satellite address by hand, a node id prefix can also be added to defeat MITM attacks with unknown satellites.
When running uplink setup, satellite addresses can now be of the form 12EayRS2V1k@us-central-1.tardigrade.io (not even using a full node id) to ensure that the peer contacted is the peer that was expected. When using a known satellite address, the known node ids are used if no override is provided.
all of the packages and tests work with both grpc and
drpc. we'll probably need to do some jenkins pipelines
to run the tests with drpc as well.
most of the changes are really due to a bit of cleanup
of the pkg/transport.Client api into an rpc.Dialer in
the spirit of a net.Dialer. now that we don't need
observers, we can pass around stateless configuration
to everything rather than stateful things that issue
observations. it also adds a DialAddressID for the
case where we don't have a pb.Node, but we do have an
address and want to assert some ID. this happened
pretty frequently, and now there's no more weird
contortions creating custom tls options, etc.
a lot of the other changes are being consistent/using
the abstractions in the rpc package to do rpc style
things like finding peer information, or checking
status codes.

It provides an abstraction around the rpc details so that one
can use dprc or gprc with the same code. It subsumes using the
protobuf package directly for client interfaces as well as
the pkg/transport package to perform dials.

* added scopelint and correcte issues found
* corrected scopelint issue
* made updates based on Ivan's suggestions
Most were around naming conventions
Some were false positives, but I kept them since the test.Run could eventually be changed to run in parallel, which could cause a bug
Others were false positives. Added // nolint: scopelint
* small identity refactor:
+ Optimize? iterative cert chain methods to use array instead of slice
+ Add `ToChain` helper for converting 1d to 2d cert chain
TODO: replace literal declarations with this
+ rename `ChainRaw/RestChainRaw` to `RawChain/RawRestChain`
(adjective noun, instead of nound adjective)
* add regression tests for V3-1320
* fix V3-1320
* separate `DialUnverifiedIDOption` from `DialOption`
* separate `PingNode` and `DialNode` from `PingAddress` and `DialAddress`
* update node ID while bootstrapping
* goimports & fix comment
* add test case
* separate TLS options from server options (because we need them for dialing too)
* stop creating transports in multiple places
* ensure that we actually check revocation, whitelists, certificate signing, etc, for all connections.
