Setter method for stratum, mapped from YANG variable /system/ntp/servers/server/state/stratum (uint8)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_stratum is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_stratum() directly.

    YANG Description: Indicates the level of the server in the NTP hierarchy. As
stratum number increases, the accuracy is degraded.  Primary
servers are stratum while a maximum value of 16 indicates
unsynchronized.  The values have the following specific
semantics:

| 0      | unspecified or invalid
| 1      | primary server (e.g., equipped with a GPS receiver)
| 2-15   | secondary server (via NTP)
| 16     | unsynchronized
| 17-255 | reserved
