Rename dir 'block' to 'storage'
Renaming the 'block' directory to 'storage', because I plan toplace code there that is related to file storage and leavingit named 'block' would be misleading.
Split DRBD8Dev into DRBD8 and DRBD8Dev
All functionality specific to a single DRBD8 devide is now in DRBD8Dev,whereas functionality which is valid for the whole DRBD "installation" on a device is collected in DRBD8.

Note that I haven't completely disabled the NodeMaintenance class withENABLE_CONFD = False because I think they are at two different levels...
DeprecationWarning fixes for pylint
In version 0.21, pylint unified all the disable-* (and enable-*)directives to disable (resp. enable). This leads to a lot ofDeprecationWarning being emitted even if one uses the recommendedversion of pylint (0.21.1, as stated in devnotes.rst)....
