Skip offset provider when connectivity is missing

[tehrengruber]

The IconGrid is missing some connectivities (that are present in the simple_grid). For example 7696d1a introduced the offset provider for C2CECEC, but we do not construct the respective connectivity. This PR just skips all offset providers for which the respective connectivity does not exist and prints a warning. This fixes executing with the icon grid again.

EDIT: Blocked by #372

It seems that you need to write one line per comment, in order to trigger each job. Please also trigger cscs-ci run benchmark in order to see how it affects benchmark execution.

The benchmark fail has nothing do do with your change. We had changed the TESTDATA mount at the same time. Sorry. You will have to rerun with TEST_DATA_PATH: "/project/d121/icon4py/ci/testdata"

[halungge]

Looks good to me. Can you open an issue in icon4py that we properly calculate the connectivity and add it to the grid? We will need to work on the grid anyway in some upcoming projects.

Forgot to submit the issue yesterday... Here we go: #374
