zipl-editenv: added zIPL multienvironment support

Browse Source 
. Support multiple namespaces in the installed environment block;
. Add option --site (-S) to specify a particular namespace
  when operating on the installed environment block;
. Add option --effective-site (-E) to specify a particular
  namespace. When using in a combination with the option -l
  (--list), it displays zIPL environment that would take place if
  the specified namespace was activated at boot time;
. Modify set/unset/reset/list operations over the installed
  environment block in the case when the option --site is specified
