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.

Map holding expected results was defined in multiple places, making test
cases a bit hard to read. This way we can change our expectations of
good results in one place and have them affect multiple test cases.
in this commit:
- centralize logging output handler.
- set global Info/Debug/Error log levels based on config file or flags.
- remove per-plugin debug arg handling.
- add a I!, D!, or E! to every log message.
- add configuration option to specify where to send logs.

Due to quite real problem of generating vast number of data series through
mesos tasks metrics this feature is disabled until better solution is found.
Also consolidated the translation code to obtain all info with just 1 command execution.
Also split test command mocks out to their own file for cleanliness.
The default is 0 so we hit a division by 0 error and crash. This checks
ensure we will not crash and `log` and continue to let telegraf run
Also we set default allow pending message number to 10000
* 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

* 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.
