great.

Here's what I propose in terms of request:
- route: 
/logs/taskmanagers/:taskmanagerid
- params:
from: starting timestamp
to: ending timestamp
limit: limit results nr

- order: timestamp DESC
- without params, return an arbitrary number of most recent log messages
- with limit only, return the most recent ones limited to 'limit'
- from < timestamp <= to
- with 'to' omitted, return from 'from' to the most recent

response:
{code}
[
  { 
     message: log message,
     level: log message level,
     timestamp: unix timestamp
  },
  {
    ...
  },
...
]
{code}

I could parse the log lines but using the proposed way we're independent of the log format.

What do you think?

> This needs addition on the server side, as the log files need to be transferred   to
the JobManager via the blob server.
