monolog() function not found [#1997462]

It looks like Drupal automagically detects that monolog_logging implements hook_watchdog(), so it loads that module before the one it depends on. Therefore under some conditions the monolog() function is not found and fatal errors are thrown.

See bootstrap_hooks() for reference.

More specificall, since Drupal sets the "bootstrap" flag to 1 in the system table for monolog_logging, it is loaded in the DRUPAL_BOOTSTRAP_VARIABLES bootstrap phase whereas the monolog module is loaded in the DRUPAL_BOOTSTRAP_FULL phase. We have a few options.

Set the bootstrap flag to 1 for all modules that monolog_logging depends on (monolog, composer_manager, ctools)
Silently ignore any watchdog logs that are called when the monolog() function is not available.
Load the modules that monolog_logging depends on (monolog, composer_manager, ctools) when the monolog() function is unavailable().

To simulate this error, hack core and throw a watchdog() call in drupal_bootstrap() during the DRUPAL_BOOTSTRAP_SESSION phase.

Pushing forward with solution #3 since we probably don't want to do a full Drupal bootstrap, and if something is logged early in the bootstrap phase then we probably don't want to silently ignore it either.

The attached patch adds a partial bootstrap process that loads the minimum subsystems and modules required for Monolog logging.
