Like for this docker containers runnings, we may know signoz/frontend is for, but why do we have gliderlabs/logspout[signoz-logspout] ?

and similarly for other containers.

We can add a description section right below the output section covering mainly these things:-

1. Name of the container
2. Is it optional or required
3. Description why that container is needed, what it does, can it be removed or will things break if we remove it.
4. more details if necessary.

It can be added for architecture of SigNoz section as well

Reason? I recently got asked about why do we have so many pods/containers of SigNoz during its installations, I was asked what are all these and why we need each one of them, I wasn't able to answer to all because it wasn't mentioned anywhere in the docs.

p.s - I made the use SigNoz for logs in prod.
