Impl commands disable

[danielealbano]

This PR introduces a new mechanism to disable commands via the config file, a new parameter called disabled_commands has been introduced.

The PR changes the following things:

• at the start, in the redis program ctor, the code checks if there is a list of disabled commands defined in the config and if yes builds an hashtable out of the list
• every time a command is found in the commands info hashtable, it's checked against the list of disabled commands and if the command is disabled returns an error
• at the shutdown, the redis program dtor hook is used to free up the hashtable with the disabled commands
