This adds a new `/upload/config` endpoint to the API for uploading encrypted configuration files for later use by the deployer.
The payload takes the form:
```
authorized:
- accounta
- accountb
config:
env:
FOO: bar
BAR: baz
```
The request is the encrypted using the deployer's public key (discoverable from its `WebappDeployer` record). This is handled automatically by `laconic-so` but can also be handled manually using standard CLI tools like `gpg` and `curl`.
For example:
```
# Get the key
$ laconic -c ~/.laconic/testnet-a-cercio.yml registry name resolve lrn://laconic/deployers/webapp-deployer-api.dev.vaasl.io | jq -r '.[0].attributes.publicKey' | base64 -d > webapp-deployer-api.dev.vaasl.io.pgp.pub
# Import it
$ gpg --import webapp-deployer-api.dev.vaasl.io.pgp.pub
# Encrypt your config file.
$ gpg --yes --encrypt --recipient webapp-deployer-api.dev.vaasl.io --trust-model always config.yaml
# Post it
$ curl -s -X POST -d '@config.yaml.gpg' https://webapp-deployer-api.dev.vaasl.io/upload/config | jq
{
"id": "B56C65AB96B741B7B219520A3ABFCD10"
}
```
