- Throw an error if there is more than one known socket on the host. - Remove the special handling for docker+containerd. - Remove the local instances of constants for endpoints for Windows / Unix and use the defaultKnownCRISockets variable which is populated from OS specific constants. - Update error message in detectCRISocketImpl to have more details. - Make detectCRISocketImpl accept a list of "known" sockets - Update unit tests for detectCRISocketImpl and make them use generic paths such as "unix:///foo/bar.sock".
