Updates Icepack consistent with CICE PR #32

* icepack_parameters: optionally compute 'dragio' from under-ice roughness

In some applications, we want the ice-ocean drag coefficient 'dragio'
to be computed using an under-ice roughness length and the thickness of
the first ocean level instead of imposing its value directly.

Add a new boolean flag 'calc_dragio' and real parameters 'iceruf_ocn',
'thickness_ocn_layer1', where 'iceruf_ocn' is the under-ice roughness
length, and 'thickness_ocn_layer1' is the thickness of the first ocean
level, to module 'icepack_parameters'.

With 'calc_dragio = .true.', compute the ice-ocean drag coefficient
following [1]. Update the documentation accordingly.

* Add 'calc_dragio' to namelist and add a test

Add the 'calc_dragio' flag introduced in the previous commit to the
Icepack namelist.

Add a test for the new feature in the base_suite.
