@brief Returns last error in esp_tls with detailed mbedtls related error codes. The error information is cleared internally upon return

@param[in] client The esp_http_client handle @param[out] esp_tls_error_code last error code returned from mbedtls api (set to zero if none) This pointer could be NULL if caller does not care about esp_tls_code @param[out] esp_tls_flags last certification verification flags (set to zero if none) This pointer could be NULL if caller does not care about esp_tls_code

@return - ESP_FAIL if invalid parameters - ESP_OK (0) if no error occurred - specific error code (based on ESP_ERR_ESP_TLS_BASE) otherwise
