This embeds a tiny TFTP server which serves UEFI iPXE which embeds a
script that chainloads a given iPXE script.

It works well for small clusters, but with bigger clusters it puts too
much load on the discovery service, as it has quadratic complexity in
number of endpoints discovered/reported from each member.

Reimplement `gopacket.PacketSource.PacketsCtx` as `forEachPacket`.
- Use `ZeroCopyPacketDataSource` instead of `PacketDataSource`. I didn't find any specific reason why `PacketDataSource` exists at all, since `NewPacket` is doing copy inside if you don't explicitly tell it not to.
- Use `WillPool` to pool packet buffers. It doesn't fully remove allocations, but it's a safe start.
Send packets back into the pool after we are done with them.
- Pass `Packet` directly to the closure instead of waiting for it on the channel. We don't store this packet anywhere so there is no reason to async this part.
- Drop `time.Sleep` code in `forEachPacket` body.
- Drop `SnapLen` support in client and server since it didn't work anyway (details in the PR).

This commit deprecates those things:
- Removes the support of `.persist` flag. From now, it should always be enabled or not defined in the config.
- Removes the documentation for `.bootloader`. It never worked anyway.
- Adds a warning for `.machine.install.extensions`, suggests to use boot-assets.

First of all, it breaks our backwards compatibility promises and breaks
documentation generation. Upstream `specs.Mount` might change at any
time.
The issue was that containerd 1.7.x brings in new `specs.Mount` which
contains extra fields which don't have `omitempty` for YAML, so
machinery always generates them which confuses old Talos versions.
Use a copy of the upstream struct with proper YAML tags, and also
provide a special trick to make sure if the upstream struct changes, we
have a chance to update our copy of the struct.
Also this fixes docs and JSON schema.
