Cache setting is missing the 'deliver' action

[jsierles]

Fastly supports 'deliver' in its UI for cache settings, so this provider should add the option as well as cache, pass and restart.

Hi @jsierles thanks for opening this issue (and your patience waiting for a reply).

Upon investigating the available actions in the UI we find that the 'Deliver' option is in fact passing a value of 'cache':

Which is already supported in Go-Fastly:

go-fastly/fastly/cache_setting.go

Lines 10 to 19 in f435b95

	const (
	// CacheSettingActionCache sets the cache to cache.
	CacheSettingActionCache CacheSettingAction = "cache"
	// CacheSettingActionPass sets the cache to pass through.
	CacheSettingActionPass CacheSettingAction = "pass"
	// CacheSettingActionRestart sets the cache to restart the request.
	CacheSettingActionRestart CacheSettingAction = "restart"
	)

If you have any further queries then please just let me know. I'll leave this issue open for a little longer to give you a chance to review and either close it yourself or raise questions, otherwise if there is no further discussion required by the end of the week I'll close this issue.

Thanks.
