Add Bolt as a Payment Method Option

[piyushswain]

This PR adds bolt as a payment method option during solidus installation.
The install_generator.rb file has been updated to add Bolt as an optional payment method during solidus installation.

The Bolt option in the payment method installs the solidus_bolt gem.

Thanks, @piyushswain!

I left a comment. Also, if you rebase from master CI will be green.

I don't think we should rely on a transitive dependency. Although it's unlikely, in the case of solidus_bolt stopping depending on solidus_auth_devise, we want the host application to keep using it.

It looks like solidus_social needs to be adapted so that it no references constants in initializers. See the Rails guides for context.

@piyushswain can you take care of it?

[waiting-for-dev]

As it contains code referencing solidus_frontend, we need to move it to the solidus_frontend installer.

[piyushswain]

@waiting-for-dev Could you please explain a little more on why we need to move the bolt installation to the solidus_frontend installer.

From what I understand solidus installation should install any selected payment_method and solidus_frontend should install the new frontend.

I don't understand the reason why we need to move this to solidus_frontend.

[waiting-for-dev]

Sure, @piyushswain. Sorry for not being clear enough. Since #4490, the Solidus installer prompts the user to select solidus_frontend or solidus_starter_frontend as storefront. The solidus_bolt extension injects code to solidus_frontend, so the extension won't work when users select solidus_starter_frontend. As the installer delegates to the solidus frontend installer when that's selected, we need to add that logic there.

We're now recommending extensions not to add storefront code. We're still missing a discussion about how we should tackle this kind of built-in integration for the new recommended frontend, though.

Does it make sense?
