v3.0.0

• RxJava2 support 🎉🎉🎉
• Add asRxMaybe().
• executeSQL() now can be executed via asRxCompletable().
• Add interceptors for ContentResolver.
• Add ContentResolver sample.
• Android gradle plugin 3.0.1 and support libraries 27.0.2.
• Mockito 2.13.0 and Mockito-Kotlin 1.5.0.
• Add gradle versions plugin.
• Table generation with few primary keys.
• Do not publish jar for android modules.

Migration notes:

• asRxObservable -> asRxFlowable (see backpressure 2.0).
• Get object asRxFlowable() and asRxSingle return Optional of object because RxJava2 no longer accepts nulls.
• You can use asRxMaybe to retrieve value without wrapping.
• PreparedOperation takes 3 parameters: Result - type of operation result; WrappedResult - Optional in cases when result may be null, result itself otherwise; Data - some operation description that can be used inside interceptor.
• You can call DefaultStorIOContentResolver.Builder#addInterceptor(Interceptor) to log/debug/modify result of any operation (like it was implemented before in DefaultStorIOSQLite).
