Set value for uses_bulkdata_default to False

[SuperMatt]

This changes the default value of uses_bulkdata to false, meaning that we can then remove the puppet hiera value which makes the default false that way. Everywhere that puppet is installed has a default value of False, so this shouldn't require a big bounce.

if we don't anticipate ever changing this default again, i'd say we could further clean this up and hardcode the default to false

(also, looks like there's some tests that were expecting the previous default)

@nemacysts the plan is to loop back and remove this once we've removed defaults from puppet in https://github.yelpcorp.com/sysgit/puppet/pull/13980 - but doing that without this change would cause a big bounce

@timmow sorry, I meant that we could get rid of get_uses_bulkdata_default() and replace any calls to that with False - then the puppet code can be removed without needing to come back to this file :)
