DAOS-16446 test: HDF5-VOL test - Set object class and container prope… (

#15004) #15098

In HDF5, DFS, MPIIO, or POSIX, object class and container properties are defined
during the container create. If it’s DFS, object class is also set to the IOR
parameter. However, in HDF5-VOL, object class and container properties are
defined with the following environment variables of mpirun.

HDF5_DAOS_OBJ_CLASS (Object class)
HDF5_DAOS_FILE_PROP (Container properties)

The infrastructure to set these variables are already there in run_ior_with_pool().
In file_count_test_base.py, pass in the env vars to run_ior_with_pool(env=env) as a
dictionary. Object class is the oclass variable. Container properties can be
obtained from self.container.properties.value.

This fix is discussed in PR #14964.
