chore(deps): cargo upgrade

I backed out a few changes:

```
Upgrading grok v~1.0.1 -> v1.2.0
Upgrading async-graphql-warp v=2.6.4 -> v2.8.2
Upgrading once_cell v1.3 -> v1.7.2
Upgrading async-graphql v=2.6.4 -> v2.8.2
```

Due to incompatibilities in package dependencies.

I backed out

```
Upgrading db-key v0.0.5 -> v0.1.0
```

Because it requires code changes.
