By default same value that was hardcoded is used, but with the
new flag added the number of scrapes can be increased to any value.

This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends.
This makes the API easier to consume and implement. In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

When printing the error, we still need access to the mmapped byte array
of the file. Therefore, we make sure that we run it before closing the
file.
I could have done something more complex like a defer, or not closing
the file, knowing that we would exit the program anyway. However, I
think that in case we extend this in the future, or this is copy/paster
elsewhere, we should continue closing the file. As it is small enough, I
went for the solution to call the function 3 times instead of playing
with a defer.

I initially thought I could somehow rescue the current column layout
by recycling the tabwriter, but flushing completely blanks
it. However, by setting a minimum width of 13, we get a slightly
broader DURATION column but otherwise nice formatting, unless numbers
get really big, but that's OK, I guess.

* MultiError: Refactored MultiError for more concise and safe usage.
* Less lines
* Goland IDE was marking every usage of old MultiError "potential nil" error
* It was easy to forgot using Err() when error was returned, now it's safely assured on compile time.
NOTE: Potentially I would rename package to merrors. (: In different PR.
