Add deleteAllDocuments , deleteDocuments by query functions . #41

dontUseTimestampsInIndex has been deprecated for a reason.

It does not make sense to have two functions that do the same thing. Also, consider:

$es->useTimestampsInIndex(false);

Reads much nicer then

$es->dontUseTimestampsInIndex();

and makes it easier to swap around your intent for using timestamps in indexes with a configuration setting, without requiring if statements to call a different function.

With regards to deleteDocuments, if it does not work with Elasticsearch out of the box, then it might be better to put it into a seperate trait which can be added to a model. Elasticquent should not require Elasticsearch plugins to be installed for any of it's 'core' functionality.

It's also important to note that this Elasticsearch plastic is essentially just syntactic sugar for
a scan/scroll search and corresponding bulk-deletes by ID.

See my comment on a related issue here #37

It would be better that instead of requiring a plugin, that we implement the scan/scroll API and do the bulk delete natively.

This would solve the issue of having to require a plugin in Elasticsearch.
