Silent Failure
Describe the bug
In the new hash table data structures, move constructors and move assignment operators are mistakenly allowed. To avoid misuse, we should disable these features along with the default constructors for the same reason.

Expected behavior

The above sample code should produce a build error indicating that the corresponding operator has been deleted.
