Support environment variables to pass config values

[jetkiwi]

Being ability to pass config variables like credentials through environment variables would make it easier and more secure to run jamf2snipe in a container or serverless environment.

For example, the following could be passed as JAMF2SNIPE_JAMF_PASSWORD.

jamf2snipe/settings.conf.example

Lines 1 to 4 in bededc3

	[jamf]
	url = https://yourinstance.jamfcloud.com
	username = a-valid-username
	password = a-valid-password

#59 would have been one way to achieve this in a different way, however the change seems to have dissapeared.

Using the 1Password CLI for that and a 1Password Service Account.

Any news on this matter? Is this taken into evaluation?
