Current Behavior

The following methods of the ServerPushConfigurationClient are lacking and overload that accepts an arbitrary certificate group id:

1. ReadTrustListAsync
2. UpdateTrustListAsync
3. AddCertificateAsync
4. RemoveCertificateAsync

Expected Behavior

The described methods have an overload that accept a NodeId certificateGroupId for specifying to with certificate group the operation is applied, so that a consumer of the library has the possibility to update / read trust lists or add / remove certificates of any server certificate group. In order to not break existing clients I would create an overload for that. I would also fall back to the default application group if the NodeId certificateGroupId is null.

Method syntax could be like:

public async Task<TrustListDataType> ReadTrustListAsync(
    NodeId certificateGroupId,
    TrustListMasks masks = TrustListMasks.All,
    long maxTrustListSize = 0,
    CancellationToken ct = default)
{}

Is it even possible to only pass in the NodeId certificateGroupId because all the methods in the NodeSet seems to have different method ids. E.g. the method id of AddCertificate of the default application certificate group has a different method id than the default https certificate groups AddCertificate?

@Tyrrx in this case I propose the method needs do to a browse call starting from the certificateGroupID and resolve the needed methods
