Use environment variables in the API for Authentication Requirement & Visibility of Details queried from betyDB

[tezansahu]

Description

• Currently, the API enforces authentication for some endpoints while allows some others to be called without authenticated. In addition to this, we wish to have an environment variable AUTH_REQ, which if TRUE allows the above mentioned behavior, but if FALSE allows requests to all endpoints on that server to be called without the need for authentication.

• Currently, on calling the workflows & runs related endpoints, all results that exist across all host machines that satisfy the filtering criteria are returned. We would like to have an environment variable HOST_ONLY, which if FALSE would callow behavior as mentioned above, but if TRUE would restrict results belonging to the particular host only.

Proposed Solution

Implement the 2 environment variables AUTH_REQ & HOST_ONLY as mentioned in the description & add simple checks/filters to achieve the mentioned functionality.
