Text fields that accept durations should describe the allowed units

[andrewkroh]

Any variables that expect a duration should specify the accepted time units. Let's add this string to descriptions on these variables.

Valid time units are "ns", "us", "ms", "s", "m", "h".

Here's an example where this is missing:

integrations/packages/ti_misp/data_stream/threat/manifest.yml

Lines 21 to 28 in 9c9f1f3

	- name: initial_interval
	type: text
	title: Interval
	multi: false
	required: true
	show_user: true
	default: 120h
	description: How far back to look for indicators the first time the agent is started.

(btw: An even better solution would be to have a duration input type in Kibana that ensured a proper duration was given.)

A duration type has been proposed in elastic/package-spec#44 (comment).
