Use InitFlags() for command line flags

[jayesh-srivastava]

Proposal: In the current implementation, command line flags like MetricsBindAddress, LeaderElection etc. are initialized in the main() function only. We can use a separate InitFlags() function to initialize all the command line flags. This approach will ease the process of adding more command line flags in future, and will help in keeping the main() function clean. This approach will also bring this provider more in-line with other CAPx projects.
