rails server takes `-e` as an argument to specify RAILS_ENV, rails console currently does not have the same interface. This commit fixes this disparity so developers can manually specify `RAILS_ENV` or can pass in an environment with a `-e`.

When launching rails server from the command line with a rails environment specified such as `rails server RAILS_ENV=production` an error would occur since rails will try to use `RAILS_ENV=production` as it's server. 

When launching rails with a specified server such as thin `rails server thin RAILS_ENV=production` no error will be thrown, but rails will not start up in the specified environment.

This fixes both of those cases

Provide access to logger instance within TaggedLogging blocks

this improves encapsulation, simplifying occurrences like the following:

    Rails.logger.tagged("DEBUG") { Rails.logger.debug(msg) }

... by removing the need to rely on (i.e. repeat) outer variables:

    Rails.logger.tagged("DEBUG") { |logger| logger.debug(msg) }

Fixes issue #5222: DateTimeSelector builds invalid dates on leap day when discarding both day and month.
