PLTS-580 | Change policycache file location to non-root to write

[krsoninikhil]

Change description

Update the policy store path to use the /tmp folder, similar to how it's used in heka. This change is necessary due to the recent change in security which blocked the root access on the server leading to failing of file creation on currently configured location.
