add firebase remote config service

[fachrihawari]

Add Firebase Remote Config support to nuxt-fire and will resolve #48 issue

Great work, everything perfect! I love how you thought of every little detail.

Two things though:

• We don't want the users have to set the minimumFetchIntervalMillis by themselves, so I would suggest we add that (with an option to set it via nuxt.config.js) within the setup
• Same goes for defaultConfig.

As seen in Setps 1.2 and 2 here:
https://firebase.google.com/docs/remote-config/use-config-web

See my comments within the files.

Could you add that? Thanks so much :)

BTW:
I added a dev branch to which you can open pull requests to in the future, so I can approve such a change already and merge in into dev and add such details by myself before merging to master. So I don't have to ask you to do all the chances ^^'

THANKS A LOT! 👍

What about we add the following functionality here?

const optionalFetchInterval = options.remoteConfig.minimumFetchIntervalMillis
remoteConfig.settings = {
  minimumFetchIntervalMillis: optionalFetchInterval ? optionalFetchInterval : 3600000,
};

remoteConfig.defaultConfig = (options.remoteConfig.defaultConfig)

So remoteConfig is setup completely and the default values can, if needed, be passed through nuxt.config.js.

That was just a quick write up, need to do it better since this will break if options.remoteConfig doesn't exist.

here add

remoteConfig: {
   minimumFetchIntervalMillis: 3600000,
   defaultConfig: {
      'welcome_message': 'Welcome'
   }
}

And later we would also need to add a description to line 206
