Fixed a concurrency problem
...
Introduced some synchronized methods and a block in order to prevent an aparent concurrency problem with the variable 'mSelectedNode' at the NetworkService class.

Renamed method and changed its functionality
...
- Renamed the 'removeCurrentNodeAndReconnect' as 'reconnectNode' since it will not be removing nodes from the list anymore
- Adapted the sample app to work accordingly

Fixing problems with the NetworkServiceManager
...
- Removed the 'mStartingService' boolean flag from the NetworkServiceManager.
- Introducing the 'passInfo' flag, used to decide whether or not to pass the connection info to the NetworkService calling the 'bootstrapService' method.

Modify autoConnect and verifyLatency behavior
...
- Added a check to make sure autoConnect=false and verifyLatency=false throw an exception, since that combination would cause the app to never connect to a node.
- Separeted the verifyLatency and autoConnect logic, so that the apps using NetworkService can decide wether to connect or not automatically, independently of verifying the latency.

- Added a method to remove nodes from LatencyNodeProvider and implemented a HashSet to keep track of such removed nodes. The reason is that calls to this class are asynchronous and only removing a node from the mFullNodeHeap was not enough to guarantee that it was not going to be added again.
...
- Added a isRemoved variable to FullNode class, so that the object can carry itself the removal status information and be able to use the same publish subject to broadcast the status of the FullNode.
- Added a method to remove nodes from NodeLatencyVerifier, removed such nodes from pending node latency measurements map 'nodeURLMap' and publish/broadcast the FullNode information with isRemoved=true so that components listening can act accordingly.
- Make proper changes to sample app's RemoteNodeActivity so that it removes 'removed' nodes from the list.

Moving away of NetworkService and graphenej in general the decision to close connection to the current node and retry with another one just because the node does not provide the info needed in PalmPay. Graphenej has to be as app agnostic as possible so a new public method 'removeCurrentNodeAndReconnect()' was implemeted to do the removal and reconnection, and the app that uses graphenej has to decide by its own metrics to remove the current connected node and call such public method.

Added proper methods to deal with bitshares nodes that send 'trash info', which are nodes that potentially do not have installed the history plugin and thus do not respond properly to history related requests. As this information is needed for PalmPay we cannot rely on such nodes and have to try to connect to a different node.

...
- Using an HttpUrl instance as a key to the map of FullNode instances, we were using simple String here before, but turned out not to be too reliable
NetworkService
- Introducing the NodeLatencyVerifier instance into the NetworkService, and making its use optional
- In case the user opts to use the node-latency verification, the initial connection is delayed until we obtain a measurement of all nodes
- Exposing a PublishSubject, this allows users of the library to get notified of the node latency measurements
NetworkServiceManager
- A boolean flag is now used to decide whether or not to start a NetworkService instance with the node-latency verification feature ON
