Spurious no-member pylint errors

[rohanpm]

Currently, code like this:

from more_executors import Executors

with Executors.sync().with_retry() as exc:
    exc.submit(lambda x: x)

Will result in a pylint error like this:

E:  3, 5: Instance of 'SyncExecutor' has no 'with_retry' member (no-member)

In more-executors repo itself, this pylint error was silenced via pylintrc. However, the same problem will affect users of the library.

The code above does not actually have a problem - the issue is that the Executors.wrap() method fools the pylint check.

It would be good to find a way to refactor the code so it has the same meaning but doesn't trigger this pylint error.
