Drush command to get the last time that the node revision delete was made

Problem/Motivation

We don't have a command to see the value to get the last time that the node revision delete was made.

Proposed resolution

We need something like this:

drush nrd-last-execute

Will show the last time that the node revision delete was made.

Remaining tasks

None.

User interface changes

None.

API changes

Added the new drush command:

drush nrd-last-execute

Data model changes

None.
