podman search: display only name and description by default

Change the default format of `podman search` to only display the name
and the description of each image.  The index is redundant to the name
and consumes a lot of space, and other descriptors (i.e., stars,
official, automated) are specific to Docker Hub and also consume a lot
space.  Users can still use `--format` for displaying the descriptors
they want to.

Add a `--compatible` flag to offer an easy way to get them back.

Also update the man page to account for the behavior and get some fresh
data in the examples.

Motivated by a recent conversation in libimage:
