i would like to create a new telegraf config from the UI and edit it

[russorat]

We have a way to create telegraf configurations in the UI today, but clicking the button opens a modal with just a few options:

Now that we can manually edit telegraf configs in the UI, we should give the user the option to create a new telegraf config without going through the modal.

Acceptance Crit

as a user, i would like the ability to create a new telegraf configuration that i can edit manually
as a user, i would like to have the new telegraf config configured to write to my cloud instance already
as a user, i would like a way to customize the telegraf config before i save it

Notes

• Telegraf has an option to generate a new config with the telegraf config command. That should match https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf
• By default, it has the outputs.influxdb configured, but in this case, we want the outputs.influxdb_v2 configured and ready to go
• Related to i would like to add telegraf plugin configurations to a new or existing telegraf configuration #784
• I'm ok completely replacing the existing "create telegraf" experience in the app.

I agree. Possibly not even having to remove the current capabilities of the 5 "Automatically configured" plugins but move that experience within the list of plugins total. Ex: I can search for the system plugin in listed of data sources, i can pointy click my way to create a Telegraf + config for it.
