Use oslo.utils
Modules `strutils`, `timeutils` and `network_utils` from common code are
graduated in `oslo.utils`, so we can:
1. remove `novaclient.openstack.common.network_utils` and use
`oslo.utils.netutils` instead.
2. use `oslo.utils.encodeutils` and `oslo.utils.strutils` instead of
`novaclient.openstack.common.strutils`.
3. use `oslo.utils.timeutils` instead of
`novaclient.openstack.common.timeutils`.
Additional information:
- modules `importutils`, `strutils` and `timeutils` from
`novaclient.openstack.common` cannot be removed, because:
- importutils is used by apiclient and jsonutils;
- strutils is used by apiclient, cliutils and jsonutils;
- timeutils is used by jsonutils
- additional check for `safe_encode` in Py3 is required, since
If91a866d864a22d28a352152beff4c7406a27b7b was merged.
