upgrade process generates a file named config.toml but default used by 2.x is config.yaml

[russorat]

according to the influxd 2.0 help:

	A config file can be provided via the INFLUXD_CONFIG_PATH env var. If a file is
	not provided via an env var, influxd will look in the current directory for a
	config.yaml file. If one does not exist, then it will continue unchanged.

yet the upgrade process generates a file named config.toml and i don't see a reason why (there's no explicit toml syntax)

@russorat it looks like the config-parser will handle either config.yaml or config.toml. Do we want to modify the upgrade command to produce YAML, or just update the help text to match the current behavior?

[russorat]

The name of the file generated should match the default name we look for when starting 2.0. Specifically: influxd will look in the current directory for a config.yaml file

you are saying it will find either a config.toml or a config.yaml by default? if that's the case, we can simply update the text in the help message,
