This patch adds support for installing, configuring all required
ceph-iscsi related packages and daemons. ceph-iscsi requires kernel
version 4.16 or greater.
To enable set
ENABLE_CEPH_ISCSI=True
Adds new config options
CEPH_ISCSI_TARGET_IQN - the rbd-target-gw iqn to use to export volumes
CEPH_ISCSI_API_HOST - the rbd-target-api ip to use to listen on
CEPH_ISCSI_API_PORT - the rbd-target-api port
CEPH_ISCSI_API_USER - the rbd-target-api user for auth against the api
CEPH_ISCSI_API_PASSWORD - the rbd-target-api password for auth against the api
The following packages are required and their deps
tcmu-runner - this requires kernel version 4.16 and > to work. Ubuntu
doesn't have a prebuilt package for this, so we pull it down and compile it.
rtslib-fb - has a pypi package
configshell-fb - has a pypi package
targetcli-fb - doesn't have a pypi package.
ceph-iscsi - doesn't have a pypi package.
