New module - meraki_config_template (#41633)

* Implement configuration template management
- Queries or removes templates
- Can bind or unbind templates to networks
- Module is idempotent only for binding and unbinding
- Meraki does not allow template creation via API
- Integration test is tedious b/c previous bullet point
- Fixed bug in construct_path() so it won't set self.function

* PEP8 changes

* Re-enable some integration tests, use variables, and fix broken code
