@param covers: The covered type. Usually this value is
dns.rdatatype.NONE, but if the rdtype is dns.rdatatype.SIG or
dns.rdatatype.RRSIG, then the covers value will be the rdata
type the SIG/RRSIG covers. The library treats the SIG and RRSIG
types as if they were a family of
types, e.g. RRSIG(A), RRSIG(NS), RRSIG(SOA). This makes RRSIGs much
easier to work with than if RRSIGs covering different rdata
types were aggregated into a single RRSIG rdataset.

It is not an error if there is no rdataset matching I{replacement}.
Ownership of the I{replacement} object is transferred to the node;
in other words, this method does not store a copy of I{replacement}
