This PR removes the complicated session management introduced in https://github.com/juanfont/headscale/pull/1791 which kept track of the sessions in a map, in addition to the channel already kept track of in the notifier.
Instead of trying to close the mapsession, it will now be replaced by the new one and closed after so all new updates goes to the right place.
The map session serve function is also split into a streaming and a non-streaming version for better readability.
RemoveNode in the notifier will not remove a node if the channel is not matching the one that has been passed (e.g. it has been replaced with a new one).
A new tuning parameter has been added to added to set timeout before the notifier gives up to send an update to a node.
Add a keep alive resetter so we wait with sending keep alives if a node has just received an update.
In addition it adds a bunch of env debug flags that can be set:
- `HEADSCALE_DEBUG_HIGH_CARDINALITY_METRICS`: make certain metrics include per node.id, not recommended to use in prod.
- `HEADSCALE_DEBUG_PROFILING_ENABLED`: activate tracing
- `HEADSCALE_DEBUG_PROFILING_PATH`: where to store traces
- `HEADSCALE_DEBUG_DUMP_CONFIG`: calls `spew.Dump` on the config object startup
- `HEADSCALE_DEBUG_DEADLOCK`: enable go-deadlock to dump goroutines if it looks like a deadlock has occured, enabled in integration tests.

This is step one in detaching the Database layer from Headscale (h). The
ultimate goal is to have all function that does database operations in
its own package, and keep the business logic and writing separate.

Currently the most "secret" way to specify the oidc client secret is via
an environment variable `OIDC_CLIENT_SECRET`, which is problematic[1].
Lets allow reading oidc client secret from a file. For extra convenience
the path to the secret will resolve the environment variables.

This commit sets the Headscale config from env instead of file for
integration tests, the main point is to make sure that when we add per
test config, it properly replaces the config key and not append it or
something similar.

This commit injects the per-test-generated tls certs into the tailscale
container and makes sure all can ping all. It does not test any of the
DERP isolation yet.
