lib/promscrape/discovery/vultr: follow-up after 17e3d019d2
- 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.
