info, images, run, networking tests: remove some skip_if_remote()s that were added in the varlink days. All of these tests now seem to work with APIv2. help test: check that first output line from 'podman --help' is the program description (regression check for #7273). load test: clean up stray images, rewrite test to make it conform to existing convention. In the process, discover and file #7337 exec test (and networking): file #7360, and add FIXME comment to skip()s suggesting evaluating those tests once that is fixed. pod test: now that #6328 is fixed, use 'podman pod inspect --format' instead of relying on jq Various other tests: add an explanation of why test is disabled so we can more easily distinguish "this will never be meaningful under remote" vs "hey, doesn't work for now, but maybe someday".
