[DevOps]: xgcm warnings polluting test suite and yaksa leaking handlers

[tomvothecoder]

There are DeprecationWarnings from xgcm that are polluting the test suite.

Warning 1

  /usr/share/miniconda3/envs/xcdat_ci/lib/python3.11/site-packages/xgcm/grid.py:1283: DeprecationWarning: The `xgcm.Axis` class will be deprecated in the future. Please make sure to use the `xgcm.Grid` methods for your work instead.

Source:

• https://github.com/xgcm/xgcm/blob/0934c3722d0b8e4842fe8e1bc3daba2ee70f665b/xgcm/grid.py#L1282-L1288
• These warnings will always appear whenever we reference the Grid class. Idk why they decided to do this instead of having the warning in the Axis class instead.

Solution:

• Now - silence these specific deprecation warnings
• Future - The next xgcm will remove the Axis class and the deprecation warnings

Warning 2

  /usr/share/miniconda3/envs/xcdat_ci/lib/python3.11/site-packages/xgcm/grid.py:989: FutureWarning: From version 0.8.0 the Axis computation methods will be removed, in favour of using the Grid computation methods instead. i.e. use `Grid.transform` instead of `Axis.transform`
    warnings.warn(

• These warnings will always appear like the other warning.

Solution:

• Now - silence these specific deprecation warnings
• Future - The next xgcm will remove the Axis class and the deprecation warnings

Warning 3

Also a "yaksa: 10 leaked handle pool objects".

Not sure what is causing this one.
