Every change to a filter (a rule or reference removed or added, the XML
edited) undefined it and defined the new XML. libvirt refuses to
undefine a filter a running VM uses, so none of these worked on such a
filter; on an unused one a refused definition was undone by defining
the old XML without its UUID, so the filter came back as another one.
The filter is now defined again with its own UUID, which libvirt does
in place, while VMs use it too; XML it cannot parse or apply to the
running VMs is refused and reported. The XML editor shows the UUID.

Four lookups built XPath expressions from values that come from
requests (CodeQL py/xpath-injection, plus get_capabilities, which
CodeQL did not flag; the pages are for superusers):
- The architecture in the create wizard's URLs went into
arch[@name='...'] in get_emulator, get_machine_types and
get_capabilities: "nope' or '1'='1" matched every architecture. It is
now an XPath variable ($arch), which is never parsed as XPath.
- Network filter rules were found with a predicate built from the
posted action, direction and priority: a quote raised SyntaxError (an
error page). The rule is now found by comparing its attributes.
- unset_qos put the posted direction into the path, so "*" removed
every bandwidth setting. It accepts inbound and outbound, as set_qos
does; the network page shows an error for anything else.
No other XPath in vrtManager is built from a value; the remaining
expressions are constants. The tests fail on the previous code.
* Add rest framework for API: First Commit
* modify some shell scripts to make variable references safer; modify some python scripts to reduce the code complexity and cyclomatic complexity of functions.
* Add REST API for some webvirtcloud functions. Instance list/delete/create, compute list/delete/create, storages-network list/retrieve. Add swagger and redoc for API interface
* update requirements
