ylemkimon 49017ad36b Improve & fix CircleCI scripts (#1658) ...

* Improve CircleCI scripts

* Upgrade to [CircleCI 2.1 
configuration](https://github.com/CircleCI-Public/config-preview-sdk)
  * Use reusable commands and jobs with parameters, instead of aliases
* Upgrade Yarn before installing dependencies, if needed: fixes issue 
#1648, which is caused by yarnpkg/yarn#5723
* Skip Flow, Jest, and coverage report upload if only website and 
documentation are changed: fixes #1655
* Add Codecov flags: https://docs.codecov.io/docs/flags
* Set CIRCLE_PREVIOUS_BUILD_NUM empty before running 
greenkeeper-lockfile: it detects the correct build by checking it's the 
first job of the first workflow. As we run jobs parallel, the correct 
build may not be the first job.
* Remove CircleCI build artifacts for now: it's highly unlikely we'll 
use them
* Add comments for #1590 workaround

* Update name

* Fix command operator precedence

* Remove workflow version
