[Core feature] Support launchplans in pyflyte run

[eapolinario]

Motivation: Why do you think this is important?

Currently we only support launching tasks and workflows in pyflyte run. We should add support launchplans as well.

Goal: What should the final outcome look like, ideally?

We should be able to use the same experience currently offered in pyflyte run to kickoff launchplans, i.e. users should be able to execute:

> pyflyte run --remote path/to/my/file.py my_launchplan
Go to http://flyte.example.com/console/projects/flytesnacks/domains/development/executions/f6e7113930e3043e79cc to see execution in the console.
...

Describe alternatives you've considered

launchplans are an indispensable entity type in the Flyte programming model, hence it should be supported in the CLIs.

Propose: Link/Inline OR Additional context

We should add launch plans to the list of entities handled by pyflyte run in here.
