## Enhance `KubeVirtNodeDriver` Compute Driver
### Description
This pull request brings several improvements to the `create_node` method
and related functions within the `KubeVirtNodeDriver`
(`libcloud/compute/drivers/kubevirt.py`).
**Features added to `KubeVirtNodeDriver.create_node`**:
- Improved compatibility with the base `NodeDriver` class:
- Added support for the `size: NodeSize` parameter, while retaining
legacy compatibility with `ex_cpu` and `ex_memory`.
- Added support for the `auth: NodeAuthSSHKey|NodeAuthPassword`
parameter.
- Support for deployment (`deploy_node`):
- `KubeVirtNodeDriver` now supports node deployment automatically,
benefiting from the above compatibility changes.
- Support for general volume (disks) types that KubeVirt supports:
- (==Breaking change==) Modified the content of the `ex_disks` parameter
to align with the related [KubeVirt
API](https://kubevirt.io/user-guide/virtual_machines/disks_and_volumes/),
making it compatible with any volume types rather than hardcoded support for
limited volume or disk types (previously only `persistentVolumeClaim` was
supported).
- Added support for the `ex_template` parameter, allowing users to customize
the entire Kubernetes object declaring the virtual machine. This is
particularly useful for:
- Supporting advanced configurations not covered by other parameters.
- Facilitating the reuse of existing virtual machine configurations.
**Fixes**:
- `_to_node`: Improved the logic for parsing memory, eliminating crashes on
virtual machines with more than 1 GiB RAM.
- `create_node`: (==Breaking change==) Renamed the parameter from `ports` to
`ex_ports`.
- ~~Addressed various bugs in the `create_node` method, which were
eliminated during the refactor and implementation of new features.~~
**Other Changes**:
- `libcloud/compute/drivers/kubevirt.py`:
- Added a `KubeVirtNodeSize` function to assist in constructing
`NodeSize` instances for `KubeVirtNodeDriver`.
- Introduced a `KubeVirtNodeImage` function to help construct
`NodeImage` instances for `KubeVirtNodeDriver`.
- Code reorganization: Moved `DISK_TYPES` out of the `create_node` and
exported it, enabling users to access a list of supported disk types.
- Updated docstrings for new features, adhering to sphinx grammar
standards.
- `libcloud/test/compute/test_kubevirt.py`:
- Introduced tests for the `create_node` method: This method was not
tested previously.
