Support adding instances with `dstack apply`
The proposal is to allow adding instances to pools via dstack apply as a replacement for dstack pool add and dstack pool add-ssh. The instance configurations could look like:
type: instance
name:
pool:
resources:
retry:
spot_policy:
max_price:
termination_policy:
termination_idle_time:
profile:
...other profile params
type: ssh-instance
name:
pool:
ssh_key_path:
region:
port:
user:
network:
The implementation will probably require refactoring to make use of instance configurations.
I'd start with instance since it's what dstack pool currently works with. We can discuss how dstack supposed to work with clusters in a separate issue: we could expand instance configuration to be able to provision multiple cluster nodes (may be as simple as specifying nodes: 8) or introducing a separate cluster configuration.
