Docs: --is-public parameter for glance image-create has been removed

[Lucas Alvares Gomes]

In a couple of parts of our install guide we use the "--is-public True/False" parameter for the "glance image-create" command, but this command is now failing with new versions of the glance client like:

 stack@virtual-machine:~/devstack$ glance image-create --is-public True --name centos-atomic --container-format bare --disk-format qcow2 < CentOS-Atomic-Host-7-GenericCloud.qcow2 usage: glance [--version] [-d] [-v] [--get-schema] [--timeout TIMEOUT]
              [--no-ssl-compression] [-f] [--os-image-url OS_IMAGE_URL]
              [--os-image-api-version OS_IMAGE_API_VERSION]
              [--profile HMAC_KEY] [-k] [--os-cert OS_CERT]
              [--cert-file OS_CERT] [--os-key OS_KEY] [--key-file OS_KEY]
              [--os-cacert <ca-certificate-file>] [--ca-file OS_CACERT]
              [--os-username OS_USERNAME] [--os-user-id OS_USER_ID]
              [--os-user-domain-id OS_USER_DOMAIN_ID]
              [--os-user-domain-name OS_USER_DOMAIN_NAME]
              [--os-project-id OS_PROJECT_ID]
              [--os-project-name OS_PROJECT_NAME]
              [--os-project-domain-id OS_PROJECT_DOMAIN_ID]
              [--os-project-domain-name OS_PROJECT_DOMAIN_NAME]
              [--os-password OS_PASSWORD] [--os-tenant-id OS_TENANT_ID]
              [--os-tenant-name OS_TENANT_NAME] [--os-auth-url OS_AUTH_URL]
              [--os-region-name OS_REGION_NAME]
              [--os-auth-token OS_AUTH_TOKEN]
              [--os-service-type OS_SERVICE_TYPE]
              [--os-endpoint-type OS_ENDPOINT_TYPE]
              <subcommand> ...
glance: error: unrecognized arguments: --is-public True

Talking on IRC with glance devs the reason for that is because now glance defaults to the v2 API which has a non-binary visibility field. So in our guides we can:

* replace the "--is-public" parameters with the "--visibility"

OR

* export "OS_IMAGE_API_VERSION=1" when running the glance image-create commands.

    Fix docs about --is-public parameter for glance image-create

    The glance CLI now defaults to the v2 API which has a non-binary
    visibility field, therefor the "--is-public" parameter has been removed
    and "--visibility public/private" should be used instead (Note: the
    --container-format parameter is required now as well).
