#915 Add POST /oglive/set REST request
This patch allows you to update clients' database entry and PXE boot file with the specified ogLive. If you specify either an incorrect or unexisting ogLive, then, clients use the default ogLive image. You can query ogLives installed on the server with ogServer's GET /oglive/list API. If you set the oglive field to "default", then the default ogLive is used. Request: POST /oglive/set { "clients": ["192.168.56.11", "192.168.56.12"], "name": "ogLive-5.4.0-r20200629" } Response: 200 OK
