Query robot for model strings on 'left' and 'right' mounts, and return a
dict with the results keyed by mount. By default, this endpoint provides
cached values, which will not interrupt a running session. WARNING: if the
caller supplies the "refresh=true" query parameter, this method will
interrupt a sequence of Smoothie operations that are in progress, such as a
protocol run.
Example:
```
{
'left': {
'model': 'p300_single_v1',
'name': 'p300_single',
'tip_length': 51.7,
'mount_axis': 'z',
'plunger_axis': 'b',
'id': '<pipette id string>'
},
'right': {
'model': 'p10_multi_v1',
'name': 'p10_multi',
'tip_length': 40,
'mount_axis': 'a',
'plunger_axis': 'c',
'id': '<pipette id string>'
}
}
```
If a pipette is "uncommissioned" (e.g.: does not have a model string
written to on-board memory), or if no pipette is present, the corresponding
mount will report `'model': null`
