Arvados

We installed 3.0 on ARDEV and ARIND, and had problems because the cache was filling up the home quota (150gb) of the generic crunch user /home/crunchg/ with .cache/arvados/keep/ entries each few hours. This was not the case before 3.0, and there is not a easy way of configuring this (also, it is easy to confuse the keepstore cache entries with the keep-web ones in documentation, configuration and code).

In the end we solved it by changing the $HOME env var to $TMP (which was set to the LSF temp dir), but doesn't seem the proper way of handling it. Is there a better way existing or planned?
