[feature request] Add the option to skip on-demand revalidation under certain circumstances

[jean-louis]

Hi, sorry for my bad english.

There are cases where it would be nice to have the option to skip the on-demand revalidation of front end pages.

For example, it would be useful to have:

• a global skip in case you have to do batch operations on the drupal side (massive content saving)
• a selective skip for content type in case the content change is done via php cli (like recurring migrations launched with drush)

I'm currently using the following patch to skip revalidation if the php process is launched via cli, but probably add some configuration to decide these behaviors could be useful for others as well.
