fix: handle network error on SETINFO (#3295) (CVE-2025-29923)

Browse Source 
* fix: handle network error on SETINFO

This fix addresses potential out of order responses as described in `CVE-2025-29923`

* fix: deprecate DisableIndentity and introduce DisableIdentity

Both options will work before V10. In v10 DisableIndentity will be dropped. The preferred flag to use is `DisableIdentity`.
