Conditionally compile code for specific roles. This allows NimBLE options in menuconfig to reduce code size based on the roles selected (scan/advertising/central/peripheral). Significant code space can be saved by removing unnecessary roles for the application.

[Server] Implement remove Characteristics/Descriptors. (#54) This allows for adding and removing of characteristics and descriptors after initial setup of the server. When used it will send a service changed notification to all clients. The changes will not take effect until all clients have disconnected and advertising restarted.

Add connection info class and access methods to server and client. This adds the ability to access information about the current connection. A new class was created to wrap the struct ble_gap_conn_desc with methods to retrieve the connection information. Example server use: ``` for(auto i=0; i<pServer->getConnectedCount();i++) { NimBLEConnInfo connInfo = pServer->getPeerInfo(i); printf("Connected client %d info:\n", i); printf("Peer address: %s\n", connInfo.getAddress().toString().c_str()); printf("Peer ID address: %s\n", connInfo.getIdAddress().toString().c_str()); printf("Handle: %u\n", connInfo.getConnHandle()); printf("Interval: %u\n", connInfo.getConnInterval()); printf("Timeout: %u\n", connInfo.getConnTimeout()); printf("Latency: %u\n", connInfo.getConnLatency()); printf("MTU: %u\n", connInfo.getMTU()); printf("Master: %s\n", connInfo.isMaster()?
