Move the `ipv4` and `ipv6` constants to their own constant
declaration. This ensures that the `iota` expression for the `ipv4`
constant evaluates to 0, not some arbitrary value. (`iota` evaluates
to N for the Nth constant in the constant declaration; see
<https://go.dev/ref/spec#Iota>.) This is also more idiomatic, which
improves readability.
Also switch from incremental integers to bit flags, and use bitwise
operators for checking. This is more idiomatic (the integer is
treated like a set of booleans), it avoids some code duplication, and
it is necessary to avoid ambiguity. Consider the following:
const (
ipv4 = iota
ipv6
)
In the above, `ipv4` would have the value 0 and `ipv6` would have the
value 1. This would make it impossible to distinguish an IPv6-only
stack from a dual-stack configuration because `ipv6` would equal
`ipv4 + ipv6`. With bit flags this problem doesn't exist.
And put the integer holding the bit flags in a custom type with
convenience methods to improve readability.

Normally K3s will import all tarballs in the image dir on startup, and
re-import any tarballs that change while it is running.
This change allows users to opt into only importing tarballs that have
changed since they were last imported, even across restarts.
This behavior is opted into by touching a `.cache.json` file in the
images dir. This file is used to track the size and mtime of the image
files when they are imported.

This eliminates the final channel that was being passed around in an internal struct. The ETCD management code passes in a func that can be polled until etcd is ready; the executor is responsible for polling this after etcd is started and closing the etcd ready channel at the correct time.

Splits server startup into prepare/start phases. Server's agent is now
started after server is prepared, but before it is started. This allows
us to properly bootstrap the executor before starting server components,
and use the executor to provide a shared channel to wait on apiserver
readiness.
This allows us to replace four separate callers of WaitForAPIServerReady
with reads from a common ready channel.

Increases log verbosity but decreases polling frequency to avoid
spamming the console. It usually takes a couple seconds for the
apiserver to come up anyway.
