Update the way settings are loaded. Instead of loading the
entire config file now settings are loaded from the config
file on demand when the cache misses.
Improve the smart settings classes tests and add another test
for the config file loading.
Add support for variable config file path.

Refactor the initial environment settings and configuration file loading
fixing some issues loading Django settings.
Consolidate all database settings into a new single setting
called "DATABASES". This mirrors Django database setting
structure. This changes makes it possible to use configure
multiple databases and database routers from the environment
variables or configuration file.
Remove usage of django-environ. Only a small set of the
features provided by django-environ were being used.
Variable typecasting is now only YAML. YAML parsing
is implemented in code.
Previously the initial setting code added all settings
it found into the global symbol table. Now the settings
found are matched to a explicit list of allowed settings.
