Remove mandatory dependencies to 'com.codahale.metrics.*' in all modules except 'restx-monitor-admin'.
Module 'restx-monitor-admin' provides 'codahale metrics' implementation (use 'com.codahale.metrics.*' dependencies)
Module 'restx-common' provides a new 'metrics' api and a 'dummy' implementation.
Module 'restx-core' use 'codahale' metrics if in classpath, otherwise fallback to 'dummy' metrics implementation
Have to provides and 'google-app-engine' metrics implementation
Add a simple user repository without dependency to filesystem
user admin / admin
add constructor parameters: admin username and credentials
Remove codahale metrics dependencies from md.rest.json
Use MetricsRegistry Component instead of new DummyMetricsRegistry()
Use dependency injection with priority management for multiple HealthCheckRegistry
Optimize imports
Fix test when directory listing sort is not predictable
No fallback to default locale (always use Locale.ROOT as fallback)
Extract codahale metrics in module restx-monitor-codahale. Component names are Factory.METRICS_REGISTRY and Factory.HEALTH_CHECK_REGISTRY
