No function to delete Analyzers

[Kafkalasch]

The function to delete Anaylzers is missing. It is only possible to read or create some:

type DatabaseAnalyzer interface {
	// EnsureAnalyzer ensures that the given analyzer exists. If it does not exist, it is created.
	// The function returns whether the analyzer already existed or not.
	EnsureAnalyzer(ctx context.Context, analyzer *AnalyzerDefinition) (bool, Analyzer, error)

	// Analyzer returns the analyzer definition for the given analyzer
	Analyzer(ctx context.Context, name string) (Analyzer, error)

	// Analyzers return an iterator to read all analyzers
	Analyzers(ctx context.Context) (AnalyzersResponseReader, error)
}
