reconstructor: retire nondurable_purge_delay option
The nondurable_purge_delay option was introduced in [1] to prevent the
reconstructor removing non-durable data files on handoffs that were
about to be made durable. The DiskFileManager commit_window option has
since been introduced [2] which specifies a similar time window during
which non-durable data files should not be removed. The commit_window
option can be re-used by the reconstructor, making the
nondurable_purge_delay option redundant.
The nondurable_purge_delay option has not been available in any tagged
release and is therefore removed with no backwards compatibility.
