Increase cacheContextLifetime to reduce false reports (#32011)

Browse source 
Replace #32001.

To prevent the context cache from being misused for long-term work
(which would result in using invalid cache without awareness), the
context cache is designed to exist for a maximum of 10 seconds. This
leads to many false reports, especially in the case of slow SQL.

This PR increases it to 5 minutes to reduce false reports.

5 minutes is not a very safe value, as a lot of changes may have
occurred within that time frame. However, as far as I know, there has
not been a case of misuse of context cache discovered so far, so I think
5 minutes should be OK.

Please note that after this PR, if warning logs are found again, it
should get attention, at that time it can be almost 100% certain that it
is a misuse.
