[UI] sky show-gpus only shows common gpus

[ewzeng]

sky show-gpus only shows some of the most common gpus, which can be confusing (e.g. here). Here are two potential solutions:

1. Keep the current behavior, but in the output of sky show-gpus and sky show-gpus --cloud CLOUD, print

NOTE:  This list only contains the most common gpus. To see all gpus, please append `--all`.

2. Add the above warning to sky show-gpus and make sky show-gpus --cloud CLOUD print out all the gpus of CLOUD.

What do people think?

We should probably resolve this by 0.3.0 to for Lambda-only users.

*NOTE*: for most GCP accelerators, INSTANCE_TYPE == (attachable) means the host VM's cost is not included.

which is surprising.

Hmm, good idea!
