This adds two new commands: `publish-webapp-deployer` and `request-webapp-deployment`.
`publish-webapp-deployer` creates a `WebappDeployer` record, which provides information to requestors like the API URL, minimum required payment, payment address, and public key to use for encrypting config.
```
$ laconic-so publish-deployer-to-registry \
--laconic-config ~/.laconic/laconic.yml \
--api-url https://webapp-deployer-api.dev.vaasl.io \
--public-key-file webapp-deployer-api.dev.vaasl.io.pgp.pub \
--lrn lrn://laconic/deployers/webapp-deployer-api.dev.vaasl.io \
--min-required-payment 100000
```
`request-webapp-deployment` simplifies publishing a `WebappDeploymentRequest` and can also handle automatic payment, and encryption and upload of configuration.
```
$ laconic-so request-webapp-deployment \
--laconic-config ~/.laconic/laconic.yml \
--deployer lrn://laconic/deployers/webapp-deployer-api.dev.vaasl.io \
--app lrn://cerc-io/applications/webapp-hello-world@0.1.3 \
--env-file ~/yaml/hello.env \
--make-payment auto
```
Related changes are included for the deploy/undeploy commands for decrypting and using config, using the payment address from the WebappDeployer record, etc.

Implementation of a command to fetch pre-built images from a remote registry, complementing the --push-images option already present on build-containers.
The two subcommands used together allow a stack to be deployed without needing to built its images, provided they have been already built and pushed to the specified container image registry.
This implementation simply picks the newest image with the right name and platform (matches against the platform Python is running on, so watch out for scenarios where Python is an x86 binary on M1 macs).
