Notifications lifetimes cannot be set to Infinity in Advanced Settings

[nickpeihl]

Kibana version:
master

Original install method (e.g. download page, yum, from source, etc.):
from source

Describe the bug:
The Notifications section under Advanced Settings recommends setting the notification lifetime to "Infinity" to disable notifications. However, the text box only accepts numeric entries.

Steps to reproduce:

1. Open the Advanced Settings page in Kibana
2. Attempt to set any of the Notification Lifetime settings to "Infinity"

Expected behavior:
The docs should specify a number (0?) instead of "Infinity"

Screenshots (if relevant):

Would it be worthy to add somewhere in the docs or the UI the information that the banner notification settings are not related with the toast notifications and that the latest ones cannot be disabled?

Looks like the code is written to accept Infinity or 0, but the box for the setting in Kibana only takes input type number:

Tested using 6.6.1

Also verified the same behavior exists in 7.0.0

Same problem in 7.5.1

Is the workaround 0 then for now?

UPDATE:
Nope - 0 nor negative integers doesn't seem to work.

Alternate workaround would be to set a large number like 31536000000 which represents 365 days in milliseconds.

@spalger - thanks - I just tried 90days (in milliseconds) and it seemed to not like such high numbers in that field. I could be mistaken.

However, it now seems to me that the banner is always displayed for that set amount of time whenever someone logs onto Kibana (session based) - which for my use case is perfect and thus the default time to live for the message should be sufficient for me. My team manages a shared cluster and I've been having difficulty getting certain messages across to users on where they should go for support / etc :)

@TinaHeiligers I'm a little lost in the merges here. What is the correct numeric value for 'infinity'? We are still on 7.10 and '0' does not seem to work.

@ducttapecoder-vt At the moment, I don't think there is a "correct numeric value" for 'Infinity'. The UI's and underlying implementations are constantly being developed and we'll look into re-defining a definitive number in feature enhancements. That being said, I think it's best to use a sufficiently large number for your use case. Maybe start off with a month?
