Please have dnsdist -c verify it can talk to the server

• Program: dnsdist
• Issue type: Feature request

Short description

dnsdist config - in non-default place - with:

setKey("Z8JaN17Ba8zkNBx8fa11VWJYm5RwHPtf+Esp8G2KwtE=")
addLocal('127.0.0.1:5400')

Running dnsdist -c gives:

Unable to read configuration from '/usr/local/etc/dnsdist.conf'
> newRemoteLogger()
Connection closed by the server.

On the server:

Accepting control connections on 127.0.0.1:5199
> Got control connection from 127.0.0.1:49564
Got an exception in client connection from 127.0.0.1:49564: Could not decrypt message

Usecase

Mostly me being stupid and dnsdist could be nicer to me. Sending a dummy message to the server should probably suffice to check for the mismatched key.
