[dagster-fivetran] Implement base resync method in FivetranClient (da…

…gster-io#26059)

## Summary & Motivation

This PR reworks legacy resync method and implements it in the
`FivetranClient`:

-  `start_resync` is added based on legacy `start_resync`
- `start_resync` leverages `_start_sync` introduced in dagster-io#25911 
- a [resync in
Fivetran](https://fivetran.com/docs/rest-api/api-reference/connectors/resync-connector)
is historical data sync - the endpoint and result is different, but
logic around how to call and handle a resync is the same as a sync.
- a resync can be done with or without resync parameters, using a
different endpoint.

Tests mock the request API calls and make sure that all calls are made.

## How I Tested These Changes
