Fix infinite loop for temp file renames on ENOENT

For whatever reason, it appears that GlusterFS, or perhaps FUSE can
continuously return ENOENT on a rename system call even when we have
double checked that there is no reason to do so. That is a bug for
that sub system. However, our response to that bug can result in an
infinite loop, which is bad.

This code reduces that to 10 attempts.

In addition, we restructed the open retry loop to match, providing
module constants for the upper bounds of both retry loops.
