> This is a followup task to MINIFI-275. While the scope of MINIFI-275 was minifi-cpp processing of components without id fields, which are optional in config schema v1, this ticket covers all fields for all component types, either doing string checks for required fields (with useful error messages if absent) or graceful handling of missing optional fields.
> The Config Schema V1 in the minifi-java codebase will be used as a guide for which fields to treat as required and which to treat as optional. [~aldrin] - please confirm that is the correct assumption for minifi-cpp. The Java implementation can be found at [1]. Specifically, in the Java code, required fields are loaded using `getRequiredKeyAsType() and optional fields are loaded using `getOptionalKeyAsType()`
> Also in scope for this ticket is to update the config.yml examples in the minifi-cpp README.md file to make sure they are not missing required fields. During testing, it was found that one example config.yml is missing source name and destination name, which are required in config schema v1.
