move performance tests so they're easier to select/skip for runners
Drop the marker for performance tests and move them under src/maasperf.
bin/pytest doesn't look there by default, while the bin/test.perf runner only runs tests under that tree.

There was code that checked for self.bmc, even though it couldn't really
be None, except for in unit tests.
A lot of tests passed in "" as the power type, expecting to get a node
without a BMC configured. But in reality, that created a BMC with power
type "", which is invalid.

Add stats for power drivers.
Also added an attribute to BMC, so that we can track whether the BMC was
auto-detected in commissioning, or whether the user created it manually.

LP:1976516 link Script to ScriptResult when creating a new one
This was causing no script to be returned for LXD VM hosts that are not deployed by MAAS.
It also fixes commissioning data sent back from the refresh operation on LXD VM hosts to return data for both resources script (to match what regular commissioning does).
