Add runtime config support

[sickfar]

At least for cookies it's very useful to add a runtime configuration support.

For example, I have three environments: dev, staging and prod like this:

• dev.example.com
• stage.example.com
• example.com

and I have subdomains "app" and "m" which are desktop and mobile versions respectively.

I want cookie to be shared across the subdomains "app" and "m", but not across environments, so here goes runtime config:

publicRuntimeConfig: {
    auth: {
      cookie: {
        options: {
          domain: process.env.NODE_ENV?.trim() === 'production' ? (process.env.BASE_URL || '.example.com') : 'localhost',
          secure: process.env.NODE_ENV?.trim() === 'production' && !process.env.IS_DEV_ENV,
        }
      },
    },
  }
}

Right now I'm doing a dirty hack in my plugin to achieve this (and it works both client and server sides):
UPD: It does not work, so I have to recompile only :(

export function dataServicePlugin (context: Context, inject: Function) {
  // @ts-ignore
  context.$auth.$storage.options.cookie.options = { ...context.$auth.$storage.options.cookie.options, ...context.$config.auth.cookie.options }
  const service = new DataService(context)
  inject('service', service)
}

Otherwise I had to recompile my app for every environment
