CLI: set decryption time on create.

Browse source 
Added an option to set the target decryption time on database creation
for the CLI create command. This required some refactoring, in
particular the extraction of the min, max and defaut decryption times in
the `Kdf` module. Some work was done to allow changing those constant
only in the `Kdf` module, should we ever want to change them.
