   ### Which version of ShardingSphere did you use?
   master
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
   proxy
   
   ### Expected behavior
   Start successfully with -f parameter when the data source is unavailable.
   
   ### Actual behavior
   Start failed.
   ```

   ### Reason analyze (If you can)
   `ShardingSphereResourceMetaData#createStorageTypes` uses `DataSourceStateManager.getInstance().getEnabledDataSourceMap` to filter the enabeld dataSources,when `ds_0` is unavailable, the storage type of `ds_0` will be null and results in a null pointer exception.
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   ```yaml
   databaseName: sharding_db
   
   dataSources:
     ds_0:
       url: jdbc:mysql://127.0.0.1:3306/demo_ds_0?serverTimezone=UTC&useSSL=false
       username: root
       password: x
       connectionTimeoutMilliseconds: 30000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 50
       minPoolSize: 1
     ds_1:
       url: jdbc:mysql://127.0.0.1:3306/demo_ds_1?serverTimezone=UTC&useSSL=false
       username: root
       password: root
       connectionTimeoutMilliseconds: 30000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 50
       minPoolSize: 1
   ```
   Config the `ds_0` with the incorrect password and start proxy by -f parameter.
