This change adds a new "generation" field to pools, scalesets and
runners. The generation field is inherited by runners from scale sets
or pools at the time of creation.
The generation field on scalesets and pools is incremented when the
pool or scale set is updated in a way that might influence how runners
are created (flavor, image, specs, runner groups, etc).
Using this new field, we can determine if existing runners have diverged
from the settings of the pool/scale set that spawned them.
In the CLI we now have a new set of commands available for both
pools and scalesets that lists runners, with an optional --outdated
flag and a new "rotate" flag that removes all idle runners. Optionally
the --outdated flag can be passed to the rotate command to only remove
outdated runners.

This change adds a new "agent mode" to GARM. The agent enables GARM to
set up a persistent websocket connection between the garm server and the
runners it spawns. The goal is to be able to easier keep track of state,
even without subsequent webhooks from the forge.
The Agent will report via websockets when the runner is actually online,
when it started a job and when it finished a job.
Additionally, the agent allows us to enable optional remote shell between
the user and any runner that is spun up using agent mode. The remote shell
is multiplexed over the same persistent websocket connection the agent
sets up with the server (the agent never listens on a port).
Enablement has also been done in the web UI for this functionality.

This change renames a lot of variables, types and functions to be more
generic. The goal is to allow GARM to add more forges in the future.
