moves config management to config provider for X509 certificate; moves certificate from v1 to v3

[zilchms]

Functionality

• Removes the template path parameter per reasoning in #158
• exchanges extensionparameter "req_ext" to "v3_req" in order to comply with template section name
• softens the config paramters owner and group to allow integers
• changes certificate part of the class to use the generated CSR instead of just skipping it and using the private key
• removes now unused erb template
• changes defaults for certificate::x509 class parameters to fit epp template
• orders resource definitions internally with puppet arrow functions

Due to: X.509 extensions included in the request are not copied by default. X.509 extensions to be added can be specified using the -extfile option.

• adds extfile to openssl args; reads extensions from config file

Tests
