* Improve PrometheusConfig

* Fix client docs

This reverts commit a193a19d.

This adds support for enabling features in the wasm build. The `default` and
`std` feature are ignored in the build.

This reduces the usage of `Blake2Hasher` in the code base and replaces
it with `BlakeTwo256`. The most important change is the removal of the
custom extern function for `Blake2Hasher`. The runtime `Hash` trait is
now also simplified and directly requires that the implementing type
implements `Hashable`.

the proof

* Bump to alpha.3

* update gitlab-ci

This patch renames the crate for the following two reasons:

1. The prometheus-exporter crate introduces native in-process Prometheus
style instrumentation to the Substrate project. Within the Prometheus
ecosystem the term "exporter" is used for external processes exposing
metrics for e.g. the Linux Kernel. In-process exposition would be
described via the term "endpoint".

2. "prometheus-exporter" is generic and ignores the fact that it is only
usable within the context of Substrate. In addition the name
"prometheus-exporter" is already taken on crates.io.

Related to #4776 
Related to https://github.com/paritytech/polkadot/pull/832

To summarize the changes:
1. I did not manage to validate with types the service's Configuration. But I did reduce the possibility of errors by moving all the "fill" functions to their respective structopts
2. I split params.rs to multiple modules: one module params for just CLI parameters and one module commands for CLI subcommands (and RunCmd). Every command and params are in their own file so things are grouped better together and easier to remove
3. I removed the run and run_subcommand helpers as they are not helping much anymore. Running a command is always a set of 3 commands: 1. init 2. update config 3. run. This still allow the user to change the config before arguments get parsed or right after.
4. I added tests for all subcommands.
5. [deleted]

Overall the aim is to improve the situation with the Configuration and the optional parameters, add tests, make the API more consistent and simpler.

unknown_os (WASM).

This prs cleans up some of the frame benchmarking stuff:
- Move CLI into `frame-benchmarking-cli`. No frame related CLI should
exists in the default Substrate CLI.
- Move all traits and types related to frame benchmarking into the
`frame-benchmarking` trait. Frame types should be isolated in Frame.

* Initial inspect.

* WiP

* Add parsing tests.

* Finalize CLI.

* Update to latest substrate.

* Remove unused imports.

* Support ImportParams as well, to get the right pruning setting.

* Mention in docs that hash is no 0x.

* Move bytes above extrinsics.

* Switch to fill helper from sc_cli.

* Remove overwrite.

* Fix error.

* Fix error message.

* Remove extra allow.

* init_config

libp2p-0.16 allows configuring yamux through libp2p-yamux, so the
direct dependency is no longer needed.

While at it we also update to the latest versions of yamux and
nohash-hasher, though the code changes do not depend on it.

* move to node-testing/bench

* to tabs

* service: Don't depend on tokio-executor

Seems to be a leftover dependency that's not used anymore.

* offchain: Upgrade hyper to 0.13, which uses tokio 0.2

* offchain: Adapt HTTP tests to Tokio 0.2

* network: Don't transitively include tokio 0.2 in WASM

1) We don't specifically depend on Tokio codec impls
2) Conflating features in Cargo means that enabling Tokio runtime
in the native environment will also do so in WASM, where it's
obviously not implemented and causes a compilation error.

* grafana-data-source: Pull hyper/tokio only in native environment

* babe_epochAuthorship
remove test-helpers from sp-keyring, bump spec_version, impl_version

* bump Cargo.lock

* add BabeRPC to node-rpc
