Adds capability to the remote python SDK to retry requests (fixes #911) This can be configured through environment: - `LANCE_CLIENT_MAX_RETRIES`= total number of retries. Set to 0 to disable retries. default = 3 - `LANCE_CLIENT_CONNECT_RETRIES` = number of times to retry request in case of TCP connect failure. default = 3 - `LANCE_CLIENT_READ_RETRIES` = number of times to retry request in case of HTTP request failure. default = 3 - `LANCE_CLIENT_RETRY_STATUSES` = http statuses for which the request will be retried. passed as comma separated list of ints. default `500, 502, 503` - `LANCE_CLIENT_RETRY_BACKOFF_FACTOR` = controls time between retry requests. see [here](https://github.com/urllib3/urllib3/blob/23f2287eb526d9384dddeedb6f6345e263bb9b86/src/urllib3/util/retry.py#L141-L146). default = 0.25 Only read requests will be retried: - list table names - query - describe table - list table indices This does not add retry capabilities for writes as it could possibly cause issues in the case where the retried write isn't idempotent. For example, in the case where the LB times-out the request but the server completes the request anyway, we might not want to blindly retry an insert request.
