The stage job was incorrectly putting wave restarts into the gfs
directory. The forecast job looks for them in the gdas directory,
so this is updated.

Additionally, the restarts were also not being copied from the
staged directory to `$DATA`, so now they are. The process is
identical to that of non-RERUN warm starts, so the code is re-
factored a bit to avoid duplication.

Resolves NOAA-EMC#3109

Adds a new vesion file for IC directories. Unlike other version
files, this one uses an associative array instead of different
variables.

With the version file in place, the versions are updated on most
of the directories to switch to the relocated wave restarts.
