Disable ParamsParser middleware in development mode

During development its better to fail fast and display complete dump of exception, which is default behaviour.
`ParamsParser` catches original exception sometimes causing issues in complete display of exceptions. Disabling it in development mode helps track exceptions better. This can be enabled/ disabled as needed for development.

- Moved adding of `ParamsParser` middleware from application.rb to an initializer
- Added check to disable `ParamsParser` for ease of development.
