[Docs] Add information about behaviors of resource defaults and limits

[marc-union]

Description

We need clearer documentation about how Flyte sets resource defaults and limits.

From @katrogan :

Platform defaults are the defaults when no task level requests/limits are set.
If only one task level request/limit is set AND that request is under the platform limit both values will be set to whichever value was set in the task.
If only one task level request/limit is set AND that request is over the platform limit the unset value is set to the platform limit.

For full details, see the Slack thread below.

the entire config system is getting overhauled. cc @katrogan ?

[katrogan]

only a proposal for now https://github.com/flyteorg/flyte/blob/master/rfc/system/3749-sane-overridable-defaults.md

but this issue is specifically for explaining what the config options mean (there is confusion between requests and defaults)
