Disable auto cache purging when WP_IMPORTING is defined

[jmslbam]

Is your feature request related to a problem? Please describe.
When running a custom import via cronjob on a production site with WP Rocket enabled, the cache clearing (rocket_clean_domain) make the import mega slow.

Describe the solution you'd like
Instead of remove all actions like here, https://github.com/wp-media/wp-rocket-helpers/blob/master/cache/wp-rocket-no-cache-auto-purge/wp-rocket-no-cache-auto-purge.php, just don't add the actions when WP_IMPORTING is defined.

Describe alternatives you've considered
Add --skip-plugin=wp-rocket with our custom WP-CLI command.

Scope a solution ✅

I'm tempted to go further and bail-out from WP Rocket loading if WP_IMPORTING is defined. This would be the same as we do for when DOING_AUTOSAVE is defined.

We can add the constant check in rocket_init() in inc/main.php.

Estimate the effort ✅

Effort [XS]

Hola, a question, what is the specific thought about labeling this low?

Every site that is running a proper import via WP-CLI or even via WP All Import or so, wíth WP Rocket enable will profit from this.

I just came back to this ticket, because I have another project which is running a big import which just crashes because WP Rocket clears cache on every single term, post etc creation / update.

In this case the import is done via WP All Import.

Maybe this following method is a better solution, add a filter to disable the clearing of the cache.

So default is true, but through the filter it can be disabled. This way the person who is doing the import needs to disable WP Rocket knowingly and will start the generation of the cache after a import is finished.

Example from SearchWP but FacetWP and ElasticPress have a similiar filter.

add_filter( 'searchwp\index\process\enabled', '__return_false' )

Most of my bigger projects run SearchWP and FacetWP and a import, so it puts quit some stress on the server that on every post and/or creation and/or update it reindexes the SearchWP, FacetWP && clears the WP Rocket cache.

Hope the filter is a implementation where you can stand behind.

Kinds regards,
