With https://github.com/paritytech/substrate/pull/4767 a `GossipEngine`
does not spawn its own tasks, but relies on its owner to poll it. This
patch removes the unneeded executor argument and spawns the gossip
engine as an orphaned task onto the executor instead.

* Be specific about the `BitVec` generic arguments

Currently we use the default generic arguments for `BitVec`. This means
we use `BigEndian` and `u8`. These default values are not stable, with
`0.17` of the `BitVec` crate this changes. To make sure we don't break
anything in the future, make sure we explictly set the generics.
