* Use zend_bool for ini bool settings
I think that these might have uninitialized bytes
when a data type larger than zend_bool is used for the ini setting,
if the module globals are set from malloc?
(Not 100% sure if the entire structure isn't set to 0 before being used)

* add a redundancy test file
add a redundancy test file checking multiple memcached restarts
install pcntl in docker container so tests are running
add also a Vagrantfile for easier dev env setup
* fix the redundancy failover by having dataresult as null initially instead of empty string
