Jan Dittberner afe7d23c9b Implement CA information command
This commit defines command codes for planned commands and response codes for
their corresponding responses.

The health response from the HSM access component has been reduced to avoid
unnecessary data transmissions.

A new CA information command has been implemented. This command can be used
to retrieve the CA certificate and profile information for a given CA name.

The client simulator has been updated to retrieve CA information for all
CAs when the list of CAs changes.
