* Fixes#1953
The MySQL DB driver has it's own DSN parsing function. Previously we
were using the url.Parse function, but this causes problems because a
valid MySQL DSN can be an invalid http URL, namely when using some
special characters in the password.
This change uses the MySQL DB driver's builtin ParseDSN function and
applies a timeout parameter natively via that.
Another benefit of this change is that we fail earlier if given an
invalid MySQL DSN.

Previously, the graphite parser would simply overwrite any template that
had an identical filter to a previous template. This included the empty
filter.
Now we will still overwrite, but first we will sort to make sure that
the most "specific" template always matches.

* Allow numeric and non-string values for tag_keys.
According to the go documentation the JSON deserializer only produces these
base types in output:
- string
- bool
- float64
- nil
With this patch bool, float64 and nil values get converted to a string when
their field key is specified in tag_keys. Previously the field was simply
discarded.
* Updated handling of nil for passing tests.
The automated tests are less than trivial to reproduece locally for me,
so I hope CircleCI wonn't mind...
* Updated changelog entries with PR and issue links.
* separate hello and authenticate functions, force connection close at end of write cycle so we don't hold open idle connections, which has the benefit of mostly removing the chance of getting hopelessly connection lost
* update changelog, though this will need to be updated again to merge into telegraf master
* bump instrumental agent version
* fix test to deal with better better connect/reconnect logic and changed ident & auth handshake
* Update CHANGELOG.md
correct URL from instrumental fork to origin and put the change in the correct part of the file
* go fmt
* Split out Instrumental tests for invalid metric and value.
* Ensure nothing remains on the wire after final test.
* Force valid metric names by replacing invalid parts with underscores.
* Multiple invalid characters being joined into a single udnerscore.
* Adjust comment to what happens.
* undo split hello and auth commands, to reduce roundtrips
* Add ignored_databases option to postgresql configuration files, to enable easy filtering of system databases without needing to whitelist all the databases on the server. Add tests for database whitelist and blacklist.
* run go fmt on new postgresql database whitelist/blacklist code
* add postgresql database blacklist option to changelog
* remove a bad merge from the changelog
also remove locking around adding metrics. Instead, keep a waitgroup on
the ServeHTTP function and wait for that to finish before returning from
the Stop() function
