Enabling Swagger and improving the HTTP API.

**Is your feature request related to a problem? Please describe.**
Every time I need to review the code and documentation to understand how the REST API and GraphQL work, I get frustrated .

**Describe the solution you'd like**
1. I would like to see Swagger appear, which will allow you to conduct experiments directly from the browser.

2. I would also like the REST API to allow filtering of the received summary data.
For example, it would be possible to get only data on metrics for all models, or to get all the information for a specific model, knowing only its table name. This would avoid loading a large amount of information at one time, as it happens now.

**Additional context**
Sample requests

+ All information: /v1/meta
+ Model information: /v1/meta/{NameModel}
+ Information on the model field: /v1/meta/{NameModel}/{Field}
