* Improve error message when essential task failed

* client/network-gossip/bridge: Use bounded channel

Instead of returning an unbounded channel on
`GossipEngine::messages_for` return a bounded channel. For now the
channel length is determined by the amount of past messages cached in
the `ConsensusGossip`.

With a bounded channel, one can't just fire-and-forget style send into
it, but has to first check whether the channel is ready. Thus this
commit restructures `GossipEngine::poll` and introduces a
`ForwardingState` into `GossipEngine`.

* client: Replace `unsafe_rpc_expose` with an `RpcMethods` enum

which can be either Default, Safe or Unsafe. The idea is to have the
following:
|                       | --rpc-external=false  | --rpc-external=true   |
|---------------------  |-------------------    |-----------------      |
| --rpc-methods=Default |                       | unsafe calls denied   |
| --rpc-methods=Safe    | unsafe calls denied   | unsafe calls denied   |
| --rpc-methods=Unsafe  |                       |                       |
Since the previous `unsafe-rpc-expose` option was confusing.

* client: Only warn against exposing externally unsafe RPC method set

* Apply suggestions from code review

* cli: Rephrase doc comment for rpc_methods config

* Improve debuggability of build_spec_works

...by printing to stderr the stderr of the command. This is normally
suppressed for succesful tests but not for failing ones - if that's the
case then it's useful to see the test failure reason inline rather than
having to execute the command separately ourselves.

* Rename RpcMethods::{Default => Auto} variant

* Update bin/node/cli/tests/build_spec_works.rs

* Expose that `BasicQueue` expects blocking spawn

Up to now `BasicQueue` expected a closure that to spawn a `Future`.
This was expected to be a closure that spawns a blocking future.
However, this wasn't documented anywhere. This pr introduces a new trait
`SpawnBlocking` that exposes this requirement to the outside.
