Dmitry eeca435064 Add rendezvous implementation for discovery interface
Update vendor

Integrate rendezvous into status node

Add a test with failover using rendezvous

Use multiple servers in client

Use discovery V5 by default and test that node can be started with rendezvous discovet

Fix linter

Update rendezvous client to one with instrumented stream

Address feedback

Fix test with updated topic limits

Apply several suggestions

Change log to debug for request errors because we continue execution

Remove web3js after rebase

// all over the place (i.e. gather it here).

// Note: it may make sense to put all stdlib Loggable functions in the eventlog
// package. Putting it here for now in case we don't want to polute it.
