Get more logs from the agent

[ys]

It is limited to 2048 for now.

I see all my ruby traces truncated... Would be cool to save the whole log somewhere on disk and just point to it too.

Or return more information to the server.

The whole log is saved on the disc in the deployment directory under logs/scripts.log
On Linux based systems it defaults to '/opt/codedeploy-agent/deployment-root///logs/scripts.log'
On Windows systems the default is 'C:\ProgramData\Amazon\CodeDeploy\logs\scripts.log'
