Support Pachyderm as integrated partner

We would like to expand our set of integrated RHODS partner offerings by adding support for Pachyderm to address use cases in the data science lifecycle. 

See epic brief for reqs: https://docs.google.com/document/d/1hYBnl7d47jRd_VABCfMW2B9W1ANLa_akx9vXEMhQPmY/edit?usp=sharing

NOTE: This will be a self-managed partner integration, meaning customers will install the application in the cluster. This is similar to other self-managed solutions like Seldon.

Reqs:

1. P0: The system must provide a Pachyderm tile in the explore tab of the RHODS dashboard. The tile must provide high-level offering benefits with clear instructions & links to enable the service.
2. P0: The system must automatically move the Pachyderm tile from the 'explore' to 'enabled' tab when an organization signs up for/installs the service. 
3. P0: The RHODS dashboard must include quickstart, tutorial, and other documentation to enable users to get started with the service and get information on common use cases.
4. P1: TBD: The system must enable integration between Pachyderm and JupyterHub and any other services (eg. Seldon Deploy) to enable an integrated user experience for key use cases.
