[Feature Request] Run Flow as Function With Variants

[sashokbg]

Is your feature request related to a problem? Please describe.
I would like to be able to load a flow as a function with 'load_flow' and specify node variants within it.

Describe the solution you'd like
N/A

Describe alternatives you've considered
Probably use the run function, but the API looks harder to use and less optimized ?

Additional context

Hi @sashokbg , currently it's not supported to directly pass variant info in load_flow API. But you can set variant info after load flow as function, here's sample code:

from promptflow.entities import FlowContext

flow_func = load_flow(path/to/flow)
flow_func.context = FlowContext(
    variant="${node_name.variant_id}",
)

flow_func(params)
