CI performance impovements (#82)

* Moved selenium to ui-e2e dev dependencies

* Cosmetics

* Removed compiling contracts from build and from test

* Introduced initialize job; Moved cover job to the main workflow

* Build, lint, test and cover jobs using initialize cache

* Yarn install not needed for oracle-e2e. Enable docker caching. Frozen lockfile

* Use docker layer caching and yarn cache for ui-e2e

* Trying to save npm install log as artifact

* More caching.
