Performs a basic sanity test on Consul configuration files. For each file
or directory given, the validate command will attempt to parse the
contents just as the "consul agent" command would, and catch any errors.
This is useful to do a test of the configuration only, without actually
starting the agent.
Returns 0 if the configuration is valid, or 1 if there are problems.`
