arccandypond tool and ENV/CANDYPOND RTE
@dcameron cache.py
library code had been reworked to arccandypond
tool.
ENV/CANDYPOND
(when requested) will copy arccandypond
tool to job sessiondir on WN and set the PATH and CandyPond URL to allow tool usage from job script.
P.S. Implements "client/cache make it candypond" cleanup task via new feature that deserves a dedicated merge request. Will be merged from master to cleanup branch.
