* fix: Update GIT_COMMITTER_NAME to use username
This was a mistake when adding the committer fields 🤦.
* fix: Use environment variables for agent authentication
Using files led to situations where running "coder server --dev" would
break `gitssh`. This is applicable in a production environment too. Users
should be able to log into another Coder deployment from their workspace.
Users can still set "CODER_URL" if they'd like with agent env vars!
This removes split ownership for workspaces. They are now
a resource of organizations and have a designated owner,
which is a user.
This enables simple administration for commands like:
- `coder stop ben/dev`
- `coder build logs colin/arch`
or if we decide to allow administrators to access workspaces,
they could even SSH using this syntax: `coder ssh colin/dev`.
This enables a "kubernetes_pod" to attach multiple agents that
could be for multiple services. Each agent is required to have
a unique name, so SSH syntax is:
`coder ssh <workspace>.<agent>`
A resource can have zero agents too, they aren't required.
