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.

* Fix cli for structopt 0.3.7 and pin to that version

This is just some hotfix to make everything compile. In the future it
will require another pr to not depend on internals of StructOpt, but
that will probably also require some additions to StructOpt itself. To
not break the code again with another StructOpt, this also pins the
StructOpt version.

* Add missing std features for runtime-io

as updated versions have been published to crates.io

* try to debug bug

* For sr-io, "std" should imply "no_oom" and "no_panic_handler".

Otherwise, rustc complains (correctly) about duplicate lang items.

* Add missing "runtime-io/std" features

* Fix compilation errors

* Prevent duplicate lang items

Rust does not allow duplicate lang items.  When compiled without the
`std` feature, `sr-io` defines two lang items.  Therefore, `sr-io`
compiled without `feature = "std"` must not be linked with `std`.

However, `pwasm-utils` and `wasmi-validation` both bring in `std` unless
compiled with `default-features = "false"`.  This caused a duplicate
lang item error.  Building both with `default-features = "false"`
prevents this error.  When building with `feature = "std"`, they should
both be built with the `std` feature, so this feature needs to be
explicitly depended on.

Three tests used 1 less gas than they had previously.
