Customer impact low. Problem occures when environment defines SEP environment variable. If this happens user can unset variable locally or use elytron subsystem for managing credential stores (alternative to elytron-tool script)

SEP for variable name is too general. It can happen running environment uses it for other purpose. Rename variable SEP in elytron-tool.* scripts (bat,ps1,sh) using namespace to ELYTRON_TOOL_SEP, as there are already variables using this namespace; ELYTRON_TOOL_RUNJAR, ELYTRON_TOOL_ADDONS.

Variable SEP is not used in any other script.
