fix data-races when running analysis

Previously when we start an analysis of language/tool we controlled the
state of execution using the monitor package, but many objects use the
same instance of monitor doing updates and reads concurrent resulting
in possible data races. This commit drops the monitor package and replace
to use the `sync.WaitGroup` to control the state of go routines.
An improvement was also made to control the timeout of analysis using
`time.After` function to receive the channel when timeout occurred or close
the `done` channel when analysis finish. An mutex was added on Service
to avoid data races when adding errors on Analysis.
