    FLUME-1215. Implement Timestamp interceptor

I ran an agent with SEQ first and then with NETCAT source. As you can see the 
channel starts, writes the seq source's output and then replays the remaining 
events when a new agent is started and writes the NETCAT events.
                
> FileChannel failing to  start, also shutdown impossible without kill

>    Affects Versions: v1.2.0
>         Environment: CentOS 5.4
>            Reporter: Juhani Connolly

> Reduced to a minimal configuration for simplicity. I can recreate this on 
> some machines, and not others. I wouldn't be surprised if it is some machines 
> specific issue(test machines on CentOS5.4. On some it worked, others not), 
> however whatever exception was thrown when attempting to get created is 
> consumed and never passed onwards
> Config:
> test.channels.ch1.type = file
> test.channels.ch1.checkpointDir = 
> /home/share/juhani_connolly/flume-1.2.0-incubating-SNAPSHOT/check
> test.channels.ch1.dataDirs = 
> /home/share/juhani_connolly/flume-1.2.0-incubating-SNAPSHOT/filechdata
> test.sources.top.type = exec
> test.sources.top.command = /usr/bin top -b -d 1
> test.sources.top.restart = true
> test.sources.top.restartThrottle = 1000
> test.sources.top.interceptors = ts
> test.sources.top.interceptors.ts.type = 
> org.apache.flume.interceptor.TimestampInterceptor$Builder
> test.sources.top.channels = ch1
> test.sinks.log.type = logger
> test.sinks.log.channel = ch1
> test.channels = ch1
> test.sources = top
> test.sinks = log
> attaching logs with general/lifecycle loglevel down to debug.
> A solution to this is probably going to be just improving error reporting.
> Another possibly more important element is that flume enters a state from 
> which it cannot shutdown without kill -9. It looks like the Interrupts are 
> getting swallowed up silently somewhere
