/**
* Creates a channel with a target string, which can be either a valid {@link
* NameResolver}-compliant URI, or an authority string.
*
* A {@code NameResolver}-compliant URI is an aboslute hierarchical URI as defined by {@link
* java.net.URI}. Example URIs:
*
* - {@code "dns:///foo.googleapis.com:8080"}
* - {@code "dns:///foo.googleapis.com"}
* - {@code "dns:///%5B2001:db8:85a3:8d3:1319:8a2e:370:7348%5D:443"}
* - {@code "dns://8.8.8.8/foo.googleapis.com:8080"}
* - {@code "dns://8.8.8.8/foo.googleapis.com"}
* - {@code "zookeeper://zk.example.com:9900/example_service"}
*
*
* An authority string will be converted to a {@code NameResolver}-compliant URI, which has
* {@code "dns"} as the scheme, no authority, and the original authority string as its path after
* properly escaped. Example authority strings:
*
* - {@code "localhost"}
* - {@code "127.0.0.1"}
* - {@code "localhost:8080"}
* - {@code "foo.googleapis.com:8080"}
* - {@code "127.0.0.1:8080"}
* - {@code "[2001:db8:85a3:8d3:1319:8a2e:370:7348]"}
* - {@code "[2001:db8:85a3:8d3:1319:8a2e:370:7348]:443"}
