that handles them properly

If we write a batch of points and get a "field type conflict" error
message in return, we should drop the entire batch of points because
this indicates that one or more points have a type that doesnt match the
database.

These errors will never go away on their own, and InfluxDB will
successfully write the points that dont have a conflict.

closes #2245

doing this unblocks incoming metrics while waiting for a flush to take
place.

we have to create a semaphore so that we can
'skip' flushes that try to run while a flush is already running.

this basically reverts #887

at some point we might want to do some special handling of reloading
plugins and keeping their state intact, but that will need to be done at
a higher level, and in a way that is thread-safe for multiple input
plugins of the same type.

Unfortunately this is a rather large feature that will not have a quick
fix available for it.
