Misc improvements (#12)

* RD: Added device-view.html for viewing and editing device details. Fixed and improved devices.html. Modified DeviceManagementController so that the '/monitor/device' endpoint returns the devices of the current user, and also plain users can retrieve info for the devices they own.

* RD: Moved 'metrics' section side-by-side to 'device info' section in device-view.html, for better viewing

* RD: changed mongo db name to 'resource_discovery' in application.yml

* RD: Minor GUI improvements

* RD: Added DeviceMonitorService to watch the status updates from EMS. Added DeviceStatusUpdate class used in DeviceMonitorService, and added field statusUpdate in Device class. Restructured and improved ResourceDiscoveryProperties.

* RD: Created AbstractMonitorService (to factor out common topic monitoring code). Renamed DeviceMonitorService to DeviceStatusMonitorService and made it subclass of AbstractMonitorService. Changed DeviceStatusUpdate class to ignore unknown properties during deserialization.

* RD: Added banner

* RD: Added DeviceMetricsMonitorService and DeviceMetrics classes. Updated Device class to store device metrics received from EMS

* RD: Updated application.yml

* RD: Added device metrics display in device-view.html. Added (EMS) device status in devices.html

* RD: Updated device-view.html to display device metrics

* RD: Modified Device in monitoring subsystem to not have its credentials serialized (and returned to browser). Also updated the affected code

* RD: Added check for a request's device IP address being in use (in another request or a registered device)

* RD: various minor code improvements

* RD: Added better error reporting in request-edit.html

* RD: Various small GUI improvements and a fix

* RD: Added archived-device-view.html, renamed archived-view.html to archived-request-view.html. Updated archived.html

* RD: Fixed DeviceManagementController to allow plain users (device owners) to access their device info (and archived devices), and control re-installing and off-boarding. Added device colouring based on their status.

* RD: Extended DeviceProcessor to check for suspect and failed devices. Added SUSPECT and FAILED statues in DeviceStatus (and in devices.html and archived.html for colouring). Added relevant settings in ResourceDiscoveryProperties. Fixed a few naming errors.

* RD: Added shortcuts (top-right corner) to all detail pages

* RD: Minor change in index.html (grayed out settings image)

* RD: Improved AbstractMonitorService (reuse of single connection, better logs). Updated affected code.

Added NODE_DETAILS in REQUEST_TYPE enum for messages sent to/received from EMS about acquiring detailed node info (including credentials). Added 'deviceInfoRequestsTopic' and 'deviceInfoReportsTopic' settings in ResourceDiscoveryProperties.

* RD: Added prompting admin to provide device credentials when un-archiving a previously archived request or device.

* RD: Moved REQUEST_TYPE enum to 'common' package and updated code

* RD: Changed authentication to use BCrypt-encrypted passwords

* RD: Fixed issue where UnknownDeviceRegistrationService registers a device before RegistrationRequestProcessor does

* RD: Modified pom.xml to build an image named 'eu.nebulous.resource-discovery' and tagged with current project version

* RD: Added 'DeviceLocation' class and 'location' field in both 'Device' classes. Also updated all 4 details pages to include Location (name, lat, lon). Fixed the Restore button of the modal dialog in archived.html to display 'Restore Request' or 'Restore Device' depending on the restore type.

* RD: Added StatusController to report current application status (currently returns 'OK')
