elasticache_parameter_group: fix KeyError bug #24475 (#24509)

Browse source 
* Fix KeyError bug by appending None if key doesn't exist

ensure value is the expected type; if if expecting something parsed as truthy try to turn it back into the desired value - fixes result showing always changed since bool compared to str

use to_text

* use string_types instead of str, remove inline conditionals, abbreviate boolean logic
