[Chore] Update API calls to use `dataset ID` instead of `name`

[jcace]

ref: https://github.com/application-research/delta-dm/pull/65 -- use this branch when testing

The updated API docs contain the new params required.

TLDR:

• Any request to the backend that references a dataset name should be changed to use the dataset ID
• The one exception to this is the POST /datasets endpoint, the request body still requires a name as the ID is auto-assigned by the database, i.e

{
    "name": "delta-test",
    "replication_quota": 6,
    "deal_duration": 540,
}

The replications page will also need the dataset column fixed:
