Jetpack Settings: Implement bulk settings management into Redux

[tyxla]

Introduction

This PR introduces actions, reducer and selectors for bulk managing (retrieving and updating) Jetpack module settings. Also, a query component for managing network requests for bulk module settings is being introduced. This PR is part of the Jetpack Module Settings group effort (#9171).

This PR will allow us to update module settings and activate/deactivate modules in a single request; also to read all module settings in a single request.

New WP.COM API methods

For interacting with the .com API it introduces 2 methods that are not yet implemented on the API side:

• fetchJetpackSettings()
• updateJetpackSettings()

In order to fully test these methods you can:

• Apply D3588-code on your .com sandbox
• Checkout REST API: Add Authentication method based on Jetpack Signatures jetpack#5418 on your Jetpack site.
• Test with the latest Jetpack to make sure you have JSON API: Add all module settings to the /settings readable endpoint jetpack#6002 on your Jetpack site (it introduces the settings retrieval endpoint).
• Connect your Jetpack site to your .com sandbox and verify they talk to each other.

To test

• Checkout this branch
• Play with the QueryJetpackSettings query component and verify it dispatches the proper network requests - <QueryJetpackSettings siteId={ 1234 } />.
• Verify all tests are working: npm run test-client client/state/jetpack-settings/settings/
