Create Template: Move default values to BE

[BrunoQuaresma]

When creating a new template, the FE must pass the default values in the API request, but this should not be mandatory so that the client can send requests with only the necessary data and be consistent.

Lines 93 to 113 in 05eac64

	max_ttl_hours: Yup.number()
	.integer()
	.min(0, "Maximum time until autostop must not be less than 0.")
	.max(
	24 * MAX_TTL_DAYS /* 30 days in hours */,
	"Please enter a limit that is less than or equal to 720 hours (30 days).",
	),
	autostop_requirement_days_of_week: Yup.string().required(),
	autostop_requirement_weeks: Yup.number().required().min(1).max(16),
	autostart_requirement_days_of_week: Yup.array().of(Yup.string()).required(),
	});
	const defaultInitialValues: CreateTemplateData = {
	name: "",
	display_name: "",
	description: "",
	icon: "",
	default_ttl_hours: 24,
	// max_ttl is an enterprise-only feature, and the server ignores the value if
	// you are not licensed. We hide the form value based on entitlements.

How can the user clear the parameter value? Let's assume that the variable/parameter is allowed to be empty, then you need to pass either the default or empty right? Unfortunately, in Golang there is no way to distinguish if the value is unset or "", and I don't want to fiddle with nulls.
