tmnxNtpPeersVarEntry represents a row in the tmnxNtpPeersVarTable
that contains the variables of a specific node associated with the
NTP server. A row is created in this table when:
an associated server is configured in the tmnxNtpServersTable,
an associated peer is configured in the tmnxNtpPeersTable, or
a peer is dynamically discovered by NTP.
