Missing OnTAP REST API calls

[SCOTT_LINDLEY]

 Several API calls are missing from the OnTAP REST interface. Many or all of these are present in the NMSDK interface. The missing commands correspond to these OnTAP commands and sub-commands:
    volume modify commands such as:

      space-nearly-full-threshold-percent

      space-full-threshold -percent

vserver security file-directory sub-commands.

These commands are critical to current automation efforts that are in progress.

Also appear to be missing the ability to set a snapmirror transfer schedule

Couple of things to be noted,
1) Verify the equivalent of ONTAPI to REST APIs using mapping document link below,

• https://library.netapp.com/ecm/ecm_download_file/ECMLP2876895 - (ONTAP 9.9.1 )
• https://library.netapp.com/ecm/ecm_download_file/ECMLP2874886 - (ONTAP 9.8) 

2) If you identify ONTAPI calls or parameters required by your automation processes that are not currently supported by the ONTAP REST API, provide the necessary information in this form so that the relevant features can be included in future updates.
