Add a new field `actorID` to the events and populate it with a UUID for the lifecycle actions `reboot`, `reset`, `upgrade` and `shutdown`. This actor ID will be present on all events emitted by this triggered action. We can use this ID later on the client side to be able to track triggered actions.
We also emit an event with an empty payload on the events streaming GRPC endpoint when a client connects. The purpose of this event is to signal to the client that the event streaming has actually started.
Server-side part of siderolabs/talos#5499.

This uses the `go-packet` library with native bindings for the packet
capture (without `libpcap`). This is not the most performant way, but it
allows us to avoid CGo.
There is a problem with converting network filter expressions (like
`tcp port 3222`) into BPF instructions, it's only available in C
libraries, but there's a workaround with `tcpdump`.

The new mode allows changing the config for a period of time, which
allows trying the configuration and automatically rolling it back in case
if it doesn't work for example.
The mode can only be used with changes that can be applied without a
reboot.
When changed it doesn't write the configuration to disk, only changes it
in memory.
`--timeout` parameter can be used to customize the rollback delay.
The default timeout is 1 minute.
Any consequent configuration change will abort try mode and the last
applied configuration will be used.

Fixes#3714
This provides more safe way to join new members to the etcd cluster.
See https://etcd.io/docs/v3.4/learning/design-learner/
With learner mode join there are few differences:
* new nodes are joined one by one, because etcd enforces a single
learner member in the cluster
* learner members are not counted in quorum calculations, so while
learner catches up with the master node, quorum is not affected and
cluster is still operational

Use `vtprobuf` optimized Marshal/Unmarshal methods which do not depend
on reflection to reduce memory and CPU usage while using Talos API.
