Add default_username/default_password as controller-only node properties
(the netmiko_device_type pattern): they are not sent to the compute,
persist with the project topology and can be updated or cleared per
node. Creating a node from a template seeds them from the template
appliance metadata, and the metadata itself is dropped there so it
never leaks into the node properties.
netmiko_device_type follows the CONTROLLER_ONLY_PROPERTIES pattern
(like console_auto_start): a node created from a template inherits the
template value, PUT /nodes can override it inside a topology, updates
never round-trip to the compute, and the value persists in the project
topology file.
Cloud and NAT nodes need live host network interface data. Previously,
GET /projects/{project_id}/nodes/{node_id} returned cached properties
from creation time, so newly added host interfaces (e.g. kernel bridges
created by EthernetSwitch nodes) were invisible until the node was
deleted and recreated.
Now the controller fetches fresh data from the compute node before
returning the response, so host interface changes are reflected
immediately. Falls back to cached data if compute is unreachable.
Previously only the "path" field was converted to a relative path for remote computes, causing issues with QEMU and VMware nodes that use different image path fields. Now all known image path fields are converted, ensuring consistent behavior across IOU, QEMU, Dynamips, and VMware node types.
When creating a node on a remote compute, the controller now sends
only the image filename instead of the absolute local path. The remote
compute will search for the image in its own configured images_directories.
If the image is not found, the compute returns ImageMissingError, which
triggers the controller's automatic image upload mechanism.
This fixes issue #2676 where remote computes reject paths from the
controller due to mismatched directory prefixes.

- Add optional `tags` query parameter to `/nodes` and `/templates` endpoints
- Support filtering by tags in format "key:value" with multiple tags ANDed together
- Example: `?tags=vendor:cisco&tags=model:7200` filters nodes/templates with both tags
- Maintain backward compatibility for existing API usage without tags parameter
