Improve metric names and use GaugeVecs for some things

Merge current master into prometheus_v0.3

* remove and reformat

* remove some more

* commit Cargo.lock

* client/authority-discovery/Cargo.toml: Update dependency

* client/authority-discovery: Pass packet payload and addresses as slice

Starting with Bytes 0.5 `Vec<T>` does not implement `Buf`, but `&[T]`
does.

* Support `u128`/`i128` in runtime interface

This implements support for `u128`/`i128` as parameters/return value in
runtime interfaces. As we can not pass them as identity, as for the
other primitives types, we pass them as an pointer to an `[u8; 16]` array.

* Remove some unsafe code usage

Remove lazy_static, use ServiceMetrics struct instead

* contracts: during execution -> contract trapped during execution

This message confused many people so we are improving it to make clear what happened.

* contracts: rename Event::Contract -> Event::ContractExecution

* contracts: fix tests after ContractExecution renaming

* contracts: Add Evicted and Restored events

* fix doc comment

* wrap to not go over (soft) 100 column line limit

* add event deposit for eventual eviction upon pay_rent

* contracts: adjust tests for the new events

* emit Evicted event immediately and add tombstone flag bool

* Pass an executor through the Configuration

* Make tasks_executor mandatory

* Fix tests

* Make debug builds more usable

This pr makes debug builds more usable in terms of `cargo run -- --dev`.

1. `--dev` activates `--execution native`, iff `--execution` is not
given or no sub `--execution-*` is given.
2. It was probably a mistake to compile WASM in debug for a debug build.
So, we now build the WASM binary always as `release` (if not requested
differently by the user). So, we trade compilation time for a better
debug experience.

* Make sure we only overwrite default values

* Make it work

* Apply suggestion

Update to paritytech/master and make a few changes

Some fixes after: https://github.com/paritytech/substrate/pull/4502

This removes the unwanted `expect`s from `MultiSigner`. Instead we
convert from full to compressed in `TryFrom` and can return an error on
invalid input.

* Initial work

* Fix most things

* fix test

* fix old comment

* migration

* fix

* remove useless stuff

* fix

* less spaghetti implementation

* fix initial session

* fix

* ci: increase retention for logs of tests to 144 hours

* change to days

* deprecate chain_status field of network handshake

* Update client/network/src/protocol/message.rs

remove unneeded whitespace.

By using `cfg(doc)`, we can generate docs for modules which are only
available from `no_std`. This drastically improves the documentation for
the developers.

* Add rules and unfounding to society.

* Docs and event

* Extra bit of docs.

* Cunningly reduce complexity

* Remove candidates when unfounding.

* Remove suspended candidates when unfounding, too.

Adds a table to the rustdoc that shows how each individual type is
passed between the wasm and the host side.
