[feat] Account creation wizard

[m4dz]

This PR introduces a new component to manage Account creation and Settings:

• [x] Create new components architecture
• [x] Only use a global state and delegate props to sub-components
• [x] Add basic layout styles to wizard view
• [x] Bind auto-discover (and auto-expanded to advanced settings)
• [x] Feedback on autodiscover errors
• [x] Add 2FA alert on Gmail accounts
• [x] Save account in Stores
• Unit test view on custom behaviors (such as magic inputs reflection)
• Test consistent component state
• Clean old account creator

[misstick]

Dont forget to hide custom configuration fields!

Ready-to-review! Still lacks:

• a better layout design
• a clever button to force closing modal instead of waiting the timeout, and a proper redirect
• dead code cleaning
• tests

But I think we can do them in another PRs :smile:.

Thanks!

In my mind, we'll be able to merge this PR when redirection to 'account/new' will work. Indeed, creation of a second account isn't possible for the moment.

Better layout design, dead code cleaning and tests can be merge in another PR.

@m4dz : shouldnt you remove old components? Is this available to edit accounts?

[misstick]

Nice work! You should remove old code that seems to conflict with the new one; keep in mind that mixins are anti-pattern and all data logic should be moved as much as possible into getters. 👍 Keep focus, and everything should be OK. I'm gonna write these things into documentation (such as mixins are anti-pattern)

@m4dz : I will merge this PR into developement but we will have to finish this review tomorrow

Yep: it's in my scope for the current sprint. If we have some extra-time, we'll probably can create the edit component that reuse the <Servers> one.
