Add logging

[JasirZaeem]

Need logging in the bot to record errors for better awareness of bugs and help in investigating them.

Current state

Errors are sent as response to the caller of the api. #11 adds logging using console.error in the errorHandler middleware which should make the errors visible on the caprover dashboard where c0d3ris deployed.

Proposed Solution

Add winston to log errors and use winston-logflare transport to forward them to our logflare account.

Or Sentry

Sentry != Logging. Sentry is a more specialized service, aimed at tracking things that are rarer/exceptional and need immediate action like app crashes, performance regressions etc. and including extra information with them that is necessary like stack traces. Logging is more general event tracking, you'd use sentry in addition to logging. Where events that are relevant to things sentry is for get sent to sentry in addition to logs.

User tries to login with incorrect credentials -> logs
User makes a post that crashes the app -> logs + sentry

Tracking every time a new feature is used -> logs, then you can analyze the logs maybe after a month to measure adoption.
New feature crashing the mobile app -> logs + sentry

@JasirZaeem Thanks for explaining the difference between the two!
