Periodically poll registries and pull images according to sync's config
Added sync on demand, syncing when clients asks for an image which
zot doesn't have.

- Show individual layers with size and digest under each image
- Include config digest for each image

Uses GraphQL API of zot to fetch CVE info
- Get all images affected by a CVE (input: CVEID)
- Get all CVEs of a layer (input: image:tag)
- Get all layers of an image which have resolved a CVE (input: image,
CVEID)
- Get all layers of an image affected by a CVE (input: image, CVEID)
Extends the existing zot CLI to add commands for listing all images and
their details on a zot server.
Listing all images introduces the need for configurations.
Each configuration has a name and URL at the least. Check 'zot config
-h' for more details.
The user can specify the URL of zot server explicitly while running the
command or configure a URL and pass it directly.
Adding a configuration:
zot config add aci-zot <zot-url>
Run 'zot config --help' for more.
Listing all images:
zot images --url <zot-url>
Pass a config instead of the url:
zot images <config-name>
Filter the list of images by image name:
zot images <config-name> --name <image-name>
Run 'zot images --help' for all details
- Stores configurations in '$HOME/.zot' file
