Rotate a security object to an existing security object.

For two keys R and S, where R is the key to be replaced, and S is the intended replacement, this operation will

• Rename R to the name provided in the request
• Establish an replaced-replacement between R and S
• Assign R's old name to S The metadata of S should be mostly same as that of R, and it is not possible to update any fields of S while performing this operation. If S does not have any custom metadata or a rotation policy, any corresponding values from R will be copied over to S. For now, this operation is not supported if R, S, or both are externally-backed keys.
