[Storage] Truncate long command str in sky storage ls

[romilbhardwaj]

Truncates long COMMAND strs in sky storage ls, like we do in sky status.

Before:

(base) ➜  ~ sky storage ls
NAME                       CREATED     STORE  COMMAND                                   STATUS
romil-debug-parq           22 hrs ago  S3     sky launch parquet_test.yaml --cloud gcp  READY

After:

(base) ➜  ~ sky storage ls
NAME                       CREATED     STORE  COMMAND                       STATUS
romil-debug-parq           22 hrs ago  S3     sky launch parquet_test.y...  READY

...

(base) ➜  ~ sky storage ls -a    
NAME                 CREATED    STORE  COMMAND                                                                                                                            STATUS  
sky-test-1688589264  1 day ago  S3     sky launch -y -c t-kubernetes-sto363-2ea4-d7 --cloud kubernetes /var/folders/98/hhq8wrtx6y13196q61xphjsm0000gn/T/tmp4ev9pbqq.yaml  INIT    
sky-test-1688589292  1 day ago  S3     sky launch -y -c t-kubernetes-sto363-2ea4-54 --cloud kubernetes /var/folders/98/hhq8wrtx6y13196q61xphjsm0000gn/T/tmpwbfcbv4x.yaml  READY  

Tested (run the relevant ones):

• Code formatting: bash format.sh
• pytest tests/test_smoke.py::TestStorageWithCredentials

I'm wondering if we should add -a option for sky storage ls as well if we are going to truncate COMMAND as a default. -a, --all would allow the user to see the full COMMAND. sky launch command with task yaml and some options used will always get truncated.

[romilbhardwaj]

@landscapepainter good idea - added -a flag to print without truncation.

Thanks for adding the support for --all @romilbhardwaj ! I tested out the flag and this should be ready to go after adding the support in the doc, docs/source/reference/cli.rst, for the newly added flag.

[romilbhardwaj]

The CLI page is auto-populated from docstrs, so it should already be there:

lgtm! @romilbhardwaj
