Shared log counter

[Naman-Monga]

Since we need to update the log counter in the capture logs task, and read it in the http server. Implemented an Arc (Mutex) to safely share the mutable reference across the service.

What's the motivation for reading it in the http server?

What's the motivation for reading it in the http server?

We want 2 features

1. to print the current log index which is exposed via a separate endpoint
2. to use the counter as the default start log id for the /history call --> will print the last offset number of logs

Can consider atomics if it's just a number
