Adding logging support for container daemon runtime error

[a0xnirudh]

As of now, the daemon is working properly but if for any chance it fails to work or it crashes, there is no way we can debug this. So logging the errors is essential. See logging class.

Solution :

Put the call to main within a try except block and then log the errors that happen during the runtime using the except block. That way, any unspecified or unmanaged errors will be caught and logged, instead of crashing directly.

I have modified the files to correspond to the solution and have made a pull request #195 .

Great. Looks like the fix is good and working. I have merged the pull request. Closing this issue now !
