Title: L1 Cache Configuration (Remote Client-Server Mode)

Describe the issue:

l1-lifespan should not be an element.

Current config:

<distributed-cache>
        ...
        <l1-lifespan="${VALUE}" />
</distributed-cache>

Should probably be something like this instead:

<distributed-cache l1-lifespan="${VALUE}" />
  ...
</distributed-cache>

Check with SMEs and update if the above is incorrect
