What does this PR do?

In disk queue configuration, it seems like the MaxRetryInterval is read from the wrong field, which leads to a panic when RetryInterval is not provided.

Also, MaxRetryInterval doesn't seem configurable at all as it is.

Why is it important?

So MaxRetryInterval can be configured

Is there any chance that this fix be backported to 7.x?

Let's wait for @faec's review here but no blocking point to have it backported in 7.17 on my side.
