- Rework for the management of mandatory components to qualify the global status. - Added qualification to components: "should", "must", "one of". - These qualifications will influence the overall state but not the unitary state of each component. Package Socket: - Creation package to open and listen local unix file socket - Allow to specify a handler who's needing a conn instance as entry - Create a client sub package to allow negociate with the local unix file socket Package Shell: - adding sub package for command and command collection Package Monitor: - add function to expose monitor command for shell Package Config: - add function to expose monitor command for shell Package Network: - Add "IP" protocol Pakcage Httpcli: - Rework the construction of the client - Add capability to specify proxy url Package Cobra: - add function to add flag to global command like verbose or config Package Log: - fix seg fault when calling a nil instance - remove println in hookfile / hooksyslog
