feat: add integration config for pachyderm input datasets (ET-12)

[corban-beaird]

Description

Originally: Adds GET endpoint for URL that points to the pachyderm input repository (if configured) associated with provided experiment. This will be used to enable basic lineage views.

Adjusted: Instead of created a redundant endpoint, we're instead formalizing the expected fields in the pachyderm integration in expconf and making it accessible through existing API calls (SearchExperiments, GetExperiment, GetRun).

Experiment Config Addition:

integration:
    pachyderm:
        dataset:
            *project
            *repo
            commit
            branch
            *token  << this is a pachd token; however, since it's scoped to the live of the experiment, paychderm preferred to be placed under dataset 
        proxy:
            *host
            *port
            *scheme
        pachd:
            *host
            *port

Test Plan

• Updated expconf tests to include the pachyderm integration config
