Complete refactoring and move to version 3.0.0

[tripflex]

So after forking this repo and updating it, adding async methods, and testing on older devices (Android only so far), specifically Lollipop and Marshmello, I think the best way to move forward is to go ahead and refactor the majority of code base to fix issues found along the way.

• Rename and switch to async promise based methods/functions
  It's 2018, if you're still using callbacks, maybe it's time to update your code base. To keep cleaner code base and easier for handling updates, and docs, going to move away from callbacks and only use promise async based functions

Refactoring

• Refactor connect to automatically add network and then enable
  Because Android doesn't actually "connect" to networks, you just add the network config and then enable the wifi, i'm going to convert the connect method to automatically add/update the wifi configuration (without throwing errors if unable to update, or add), and as long as there's a valid network ID for the SSID, enable the network .. only throwing errors when connection fails, or no net id was able to be obtained

Oreo issues for modifying existing networks, enabling/disabling/removing networks now only allow the UID that created/added the network to remove/modify, etc.

Because of this, if you want to connect to a network (which code wise is done with enableNetwork), it must be done after adding the network configuration, as only the UID that created the configuration, and modify the state

Current Known Issues

• Ping on bindall network does not work (assumption is due to using Runtime.getRuntime() but honestly not sure, don't know enough about Android to fix it at this time
  - The only reason I know this was while testing trying to ping router that does not have internet, and was unable to ... but running a standard HTTP GET request from JS worked fine ...

iOS

• Test existing methods to make sure they still work
• Update or remove any methods that no longer work

New Features

• Add permissions handling, specifically ACCESS_FINE_LOCATION to prevent requiring GPS enabled

• Add bindAll argument to enable and connect to set bindProcessToNetwork or setProcessDefaultNetwork to route all connections from application through wifi (regardless of whether wifi has internet)

• Add helper method to get wifi signal strength https://github.com/devstepbcn/react-native-android-wifi/blob/master/android/src/main/java/com/devstepbcn/wifi/AndroidWifiModule.java#L319

Connecting your App to a Wi-Fi Device
AnyDevice Example Code

• Possible integrate discontinued features from hotspot plugin Request for merging other discontinued libraries into WifiWizard2 #4

• Add methods to obtain IP address and other network information cordova-plugin-networkinterface

• Add method to check for internet access isConnectedToInternet

cordova-plugin-network-information

• Create separate classes and files to better organize all methods and classes
  After my initial fork of this plugin, things have been constantly growing and being added, resulting in a large single file with ~2k lines of code. Need to clean up code base, and move methods/functions/classes to separate files to keep clean codebase.
