* Expose information about the extrinsic in the metadata

This pr exposes some information about the extrinsic used in the runtime
via metadata. The following information are exposed:

- Version of the extrinsic
- List of all signed extensions used by the extrinsic.

* Increment `spec_version`

To my knowledge, we don't keep wasm blobs checked in anymore.

It changes the way we extended the CLI functionalities of substrate to allow more flexibility. (If this was not clear, here is another version: it changes the `sc_cli` API to allow more flexibility).

This touches a few important things:
 - the startup of the async task with tokei:
    This was in node and node-template and I moved it to substrate. The idea is to have 1 time the code that handles unix signals (SIGTERM and SIGINT) properly. It is however possible to make this more generic to wait for a future instead and provide only a helper for the basic handling of SIGTERM and SIGINT.
 - increased the version of structopt and tokei
 - no more use of structopt internal's API
 - less use of generics

Related to #4643 and https://github.com/paritytech/cumulus/pull/42: the implementation of "into_configuration" and "get_config" are similar but with better flexibility so it is now possible in cumulus to have the command-line arguments only of the run command for polkadot if we want

Related to https://github.com/paritytech/cumulus/issues/24 and https://github.com/paritytech/cumulus/issues/34 : it will now be possible to make a configuration struct for polkadot with some overrides of the default parameters much more easily.

I don't see any good reason to build with --release to test this but this step takes 8-8:30 min on the CI and I suspect we would save some time by using the debug build instead.

Patch d9837d7d reintegrated the periodic neighbor packet worker, by
moving its logic into a `Future` implementation on `NetworkBridge` which
needs to be polled by its upper layer.

Polling by the upper layer was implemented within the `Future`
implementation of the `VoterWork` struct but not within the `Future`
implementation of the `ObserverWork` struct. This patch adds polling of
the `NetworkBridge` to the latter.

This pr adds `get_global` to retrieve a `global` variable from an
instantiated sandbox wasm blob.

A light client can not be a validator, so we should not set `authority

Before we printed the error of a transaction only when importing a
block, this pr changes it to print the error also at building the block.

* WASM runtime switch to import memory

Up to now runtimes have exported their memory. To unify it with
sandboxing, this pr switches runtimes to import memory as well.

From a functional perspective, exporting/importing memory makes no
difference to the runtime.

To provide backwards compatibility, WASM exported memory is still supported.
