[CI] Speed up check_images_exist

[perangel]

What

Small performance optimization for how we check for the existence of images in tools/bin/check_images_exist.sh.

# old
./tools/bin/check_images_exist.sh all 6.31s user 3.50s system 4% cpu 3:35.97 total

# new
./tools/bin/check_images_exist.sh all  3.56s user 2.21s system 6% cpu 1:29.55 total

NOTE: The best-case scenario (no rate limit) we can get it down to ~30s

How

• We use docker compose pull to verify if an image referenced in a docker compose file exists
• Some of our images approach ~1Gb in size
• We can verify if an image exists by just calling the dockerhub API instead of performing a docker pull

Looks fantastic @perangel

[git-phu]

looks good!

Now I'm curious though about why we were pulling platform images to begin with.

@davinchia do you have any extra context around why we were pulling platform images to verify they exist instead of just checking the API response (which is what we already do for connector images anyway)?
