Remove all custom eslint rules

We should follow the eslint default, completed by the imported
scality rules.

Any additional rule should add some constraints, like disabling
.only tests to make the CI fail.

The reason is that we end up being too leniant on the style,
and that translates into useless indent (or other style) changes
in branches, due to local tooling auto-formatting the code,
which make the reviews harder.
