[Feature Request]Enable log directory for our of conatiner log inspections

**Purpose of the feature.**
When running documentdb-local I like to specify a log directory on the host to send all logs to (including postgres) so I can investigate and review them without going inside the container.

**Describe the solution you'd like**
I like to see that I can specify a volume mount `-v` to `\log` which will make all logs go to the directory I specify.
