- Remove logger as globals to use dedicated pointer (#104)

# Refactor Logger :
- Remove logger as globals to use dedicated pointer
- Add compat file to allow retro-compatibility (function are deprecated)
- Add field management to allow add custom information
- Add option struct to manage options
- Add entry struct to manage all log entry
- Add multithreading capabilities (with race prevention)
- Allow to log to file + stdout/stderr + syslog
- Add io.WriteCloser compatibility interface
- Add logrus hook to manage option by hook instance
- Add capabilities to custom each logfile/syslog/standard independently
- Add small test suite

# Update Packages for logger new options : 
- archive
- cluster
- context
- httpcli
- httpserver
- ldap
- tests

# Other : 
- bump dependancies
- update minio server for aws test
