"""Contains configuration options for NetApp drivers.

Common place to hold configuration options for all NetApp drivers.
Options need to be grouped into granular units to be able to be reused
by different modules and classes. This does not restrict declaring options in
individual modules. If options are not re usable then can be declared in
individual modules. It is recommended to Keep options at a single
place to ensure re usability and better management of configuration options.
