We introduced banning of peers who spam us with the same request (more
than 2 times). However, we missed that it is completely legal to send
the same request multiple times as long as we did not provide any
answer. An example for that is the justification request. This request
is send multiple times until we could fetch the justification from one
of our peers. So, the solution to this problem is to tag requests as
fulfilled and to start counting these fulfilled requests. If the number
is higher than what we allow, the peer should be banned.

The timestamp inherent type was up to now just a simple `u64`. This
worked, but doesn't give you that much guarantees at compile time about
the type. This pr changes that by converting this type to a unit type
wrapper, similar to what we have done for `Slot`.

This is required for some future pr that touches quite a lot of the
inherents stuff :)

Besides this unit wrapper type, this pr also moves the `OnTimestampSet`
trait to `frame_support::traits`.

* Introduce new concept of "slot portion for proposing"

Currently when building a block we actually give the proposer all of the
time in the slot, while this is wrong. The slot is actually split in at
least two phases proposing and propagation or in the polkadot case into
three phases validating pov's, proposing and propagation. As we don't
want to bring that much polkadot concepts into Substrate, we only
support splitting the slot into proposing and propagation. The portion
can now be passed as parameter to AuRa and BABE to configure this value.
However, this slot portion for propagation doesn't mean that the
proposer can not go over this limit. When we miss slots we still apply
the lenience factor to increase the proposing time, so that we have
enough time to build a heavy block.

Besides all what was said above, this is especially required for
parachains. Parachains have a much more constraint proposing window.
Currently the slot duration is at minimum 12 seconds, but we only have
around 500ms for proposing. So, this slot portion for proposing is
really required to make it working without hacks.

* Offgit feedback

* Cast cast cast

* Decrease the peer reputation on invalid block requests

This pr changes the block request handler to decrease the reputation of
peers when they send the same request multiple times or they send us an
invalid block request.

* Review feedback

* Change log target

* Remove unused code

* AuRa improvements

Hot and fresh AuRa improvements. This pr does the following:

- Move code belonging to the import queue etc to import_queue.rs
- Introduce `ImportQueueParams` and `StartAuraParams` structs to make
it more easier to understand what parameters we pass to AuRa.
- Introduce `CheckForEquivocation` to tell AuRa if it should check for
equivocation on block import. This is required for parachains, because
they are allowed to equivocate when they build two blocks for the same
slot, but for different relay chain parents.

* Make `on_slot` return the block with the post header

Before this pr `on_slot` returned the pre block. However this is wrong,
because adding some post digest changes the hash of the header. Thus,
we need to make sure to return the correct block that uses the post
header.

This pr ensures that we spawn the block import worker as an essential

block import is done. Besides that it adds some debug output to the

* Fix tracing spans are not being forwarded to spawned task (#8009)

* Fix tracing spans are not being forwarded to spawned task

There is a bug that tracing spans are not forwarded to spawned task. The
problem was that only the telemetry span was forwarded. The solution to
this is to use the tracing provided `in_current_span` to capture the
current active span and pass the telemetry span explictely. We will now
always enter the span when the future is polled. This is essentially the
same strategy as tracing is doing with its `Instrumented`, but now
extended for our use case with having multiple spans active.
