added support for first and last sibling environment variable: "ENV_SIBLING_POSITION". This value will either be "FIRST" or "LAST" or undefined.

"FIRST" means that the sibling is the first in the list of a common parent, provided that the sibling resides in the same priority group
"LAST" means that the sibling is the last in the list of a common parent, provided that the sibling resides in the same priority group
