Enable retries for all requests

[szokeasaurusrex]

We have received reports from a customer that some requests the CLI makes are failing with 502 errors, causing the CLI to fail with non-zero exit status, despite having set a very high max retry count.
However, Sentry CLI does not retry requests to the API that was failing (in this case, the GET /organizations/{}/chunk-upload/ endpoint).

We should investigate whether we can just add consistent retry logic to all of the requests that Sentry CLI makes. If this is feasible, we should just retry all requests; if it turns out that retrying all requests is not desirable, we should at least retry the chunk-upload endpoint, since we know it is blocking a customer.
