- Sort the discovered labels in alphabetical order at https://docs.victoriametrics.com/sd_configs/#vultr_sd_configs - Rename VultrConfigs to VultrSDConfigs to be consistent with the naming for other SD configs. - Prepare query arg filters for `list instances API` at newAPIConfig() instead of passing them in a separate listParams struct. This simplifies the code a bit. - Return error when bearer token isn't set at vultr_sd_configs, since this token is mandatory according to https://docs.victoriametrics.com/sd_configs/#vultr_sd_configs - Remove unused fields from the parsed response from Vultr list instances API in order to simplify the code a bit. - Remove double logging of errors inside getInstances() function, since these errors must be already logged by the caller. - Simplify tests, so they are easier to maintain.
