feat(Manifold.Worker): Allow sends with :noconnect and :nosuspend options

[jliklik]

What

Add :nosuspend and :noconnect options when sending to remote nodes.

Why

When communicating with an unreliable remote node, send/2 may block or slow down the sending erlang process due to auto-connections and overloaded connections.

:nosuspend -> Allows sending process to drop message if connection to the remote node is overloaded
:noconnect -> If remote node is not already connected, node will not try to connect to it when sending the message

These options must be used with care, as they may break the reliable message passing guarantees normally expected in erlang/elixir.

How

Use Process.send/3 with :noconnect and :nosuspend options instead of Kernel.send/2.

Testing

Added some tests for the new Manifold options and to verify that the new Process.send/3 call does not break functionality.
