Make namespaces available as named exports

[garg3133]

This PR makes the namespaces specified in the namespaced-api.js file available as named exports.

To test this PR, copy/move the navigateTo.js and getTitle.js (or any other command files) to the client sub-directory. Doing so will make those commands available on the client namespace.

In your test, use it as:

const {client, assert} = require('../../lib/index'); // path to `lib/index.js` file

describe('demo', function() {
  it('demo test', function() {
    console.log(client.navigateTo('https://ecosia.org').getTitle((result) => console.log(result)));
    console.log(await assert.titleContains('Ecosia').titleEquals('Ecosia - the search engine that plants trees'));
  });
});

In above test, the commands will return the namespace only instead of the whole browser object. While the commands executed using browser.client.commandName will still return the whole browser object.

This change here is for the discussion we had that we don't need to load all the namespaces directly onto the page objects but only a few like cookies and a11y. So, with this, we can restrict the namespaces we do not want to load on page-objects.

This was actually added here because page objects already had a client property (set to NightwatchClient) and so we could not add the client namespace commands directly onto page-objects, but it also serves the purpose mentioned above. And since we are no longer loading the commands onto client namespace, we can safely remove this as well if we do not want this feature at this point.

Great work on this pull request! LGTY!!

Windows build failing, and I suspect increasing timeout will fix the issue.

Windows build failing, and I suspect increasing timeout will fix the issue.

Maybe, but in the last 4 build failures, 5 tests failed cumulatively, and all are different. So, not sure which test to increase the timeout for if a different test fails every time.

@garg3133 maybe try increasing the default timeout?
