Subject: mgr/dashboard: fix group name bugs in the nvmeof API
X-Git-Tag: v19.2.1~151^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=4b304f719469c34a0704d41a6621ddd2e1031c90;p=ceph.git

mgr/dashboard: fix group name bugs in the nvmeof API

there are 2 issues

1. in cephadm, i was always using the first daemon to populate the group
   in all the services for the dashboard config.

2. in the API, if there are more than 1 gateways listed in the config,
   rather than chosing a random gateway from the group, raise an
   exception and warn user to specify the gw_group parameter in the api
   request
