* Apply suggestions from code review

* Fix a check for polkadot to work on forked repos.

* .gitlab-ci.yml: Add `git diff` for CI debugging

* More future proof and less redundant.

* .gitlab-ci.yml: Improve comments and refactor sed command

* .gitlab-ci.yml: Remove two commas in a row

* .gitlab-ci.yml: Ensure to match branch statements at the end

* .gitlab-ci.yml: Reference concrete commit

When one does not specify the concrete commit, cargo-update tries to
checkout 'master' in the Substrate repository.

* .gitlab-ci.yml: Remove 'git diff' debug line

* Create typed client helpers for querying chain state storage items declared by
'decl_storage!'.

* Update substrate-rpc-custom functions to use async await syntax.

* The implementation of substrate-rpc-custom was a bit verbose and repetitive.
This commit makes the implementation simpler by intruducing a struct which
represents query for a typed value in storage. The new struct is called
StorageQuery. A StorageQuery wraps a raw StorageKey but is not directy
constructable. To construct a StorageQuery, the user must supply an
implementation of a srml_support::storage::generator trait such as
StorageValue or StorageMap.

A type implementing one of the generator traits can be aquired by:
A) marking a storage item as pub within a call to decl_storage (recommended)
or B) implementing one of the generator types manually.

While option B may sometimes me necessary, it's not recommended because
separate manual implementaions may lose sync with the original definition.

* drop unused dependency

* fmt

* Remove unnecessary pub from Authorities field in test-runtime storage
declaration.

This field was added to support a test in an earlier commit. The
test no longer relies on test-runtime so the change can be reverted.

* Move it to srml as support extension.

* Fix long lines.

* Fix.

* first draft of everything that works

* Some test fixes
