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`.

* 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.

* Formatting clean up

* Introduce separate setters for the fees.

* removes use of sc-client from sc-basic-authorship

* refactor use of ProposerFactory

* correct dep path

Sadly we need to keep one function `ext_blake2_256`. This function is
manually defined in `sp-core`.

* removes use of sc_client::Client from sc_finality_grandpa

* code formatting

* code formatting

* removes use of sc_client::Client from sc_finality_grandpa

* setting first batch of descriptions

* fix what I just broke

* next batch

* and pallets, too

* last batch

* set cargo.lock

* keep'em dev-deps

* bump version to alpha.2

* Handle gas_price being zero separately

* Bump spec_version

* Add a unit & integration tests for gas price = 0

* Activate publishing of draft releases...

... And fix the message sending (missing parameter).

* publish_draft_release.sh now checks latest...

... release on github rather than just a tag

* repro ui bug

* fix the tests

* test with the new image

* test without CARGO_HOME

* test without fixes

* test again

* fix trybuild old versions

* bump CArgo.lock

* fix trybuild newest versions

* bump Cargo.lock

* run with the old image

* ci will be green on the image from 2020-02-19 [skip ci]

* bump Cargo.lock

* Adds documentation for `wipe` and `commit`

This adds documentation to `wipe` and `commit` of `Externalities`.
Besides that it removes the default implementation that would just panic
and requires that all implementers of the trait implement the functions.

* Update primitives/externalities/src/lib.rs
