WIP: posterior API's

[koolgax99]

Description

Here we extend the PEcAn API's by adding Posterior file API's. Currently, we only have 2 API's

• /api/posteriors/ which lists all the posterior files
• /api/posteriors/{posterior_id}/ which allows users to download the desired posterior file.

More information about these API's can be viewed in the Swagger documentation.

Tests are yet to be added for this API. The second API is still in progress and needs suggestions from various contributors

Review Time Estimate

• Within one week
