Our eslintrc extends from 'wikimedia/client' which includes a
'no-restricted-properties' ruleset from the 'not-es5.js' file [1].
However, we were also including our own 'no-restricted-properties'
rules.
ESLint handle this duplication by clobbering instead of merging
so eslint-config-wikimedia's no-restricted-properties where not taking
effect and we were losing out on some guards against using es6.
This commit corrects that and makes both no-restricted-properties
rulesets merge instead of clobber as already done in MobileFrontend [2]

- Enable ESLint caching with `--cache` which presumably improves
performance.
- Forbid warnings by setting `--max-warnings` to zero. Code containing
warnings should not be committed. However, warnings are still an
exceptionally useful distinction to make from errors during
development. When hacking, we do not care if a comment exceeds the
maximum line length or if a trailing space is present but we do oh so
very much care if the linter detects a likely programming error such
as forgetting to initialize a constant. The former is a warning and
the latter is an error.
- Forbid unused lint directives by enabling
`--report-unused-disable-directives`. This setting prevents outdated
ESLint error waivers from littering the code.
There is a related pull request to move these settings to defaults in
eslint-config-wikimedia itself:

This exposes two broken tests:
* #setCount (Eastern Arabic numerals)
* clicking on the product of createBanner() should trigger a custom event
that were previously passing due to buggy assertions.

stylelint is part of config, but not run by default
Also update to 0.4.1, it is the current default in many wmf extensions
