There was a problem identified where an upstream API connection was found hanging waiting
for a TLS handshake to complete. Seeingly the TCP connection was ESTABLISHED locally but
not cleanly terminated remotely. The Socket events layer never triggered the TLS handshake
oddly. This however enables TCP keep alive packets to detect broken connections, raising
EPOLLERR and breaking the deadlock condition so that the agent will attempt to reconnect
at a later time.

Recent Net-SNMP's snmpd daemon has changed behavior returning detailed
information about the network interfaces in the IF-MIB::ifDescr MIB.
There is a patch out there that is working around the issue (see also
https://bugs.debian.org/812837) by providing the behaviour via '-N'.
This path provides a way to make use of this workaround.

So we can run unit tests that expect a certain behavior based on time.
When Icinga 2 is compiled with I2_DEBUG one can use Utility::SetTime to
override the current system time, and lock it to this value.

Adds a new configuration variable in keeping with the graphite writer
which defaults to false to save network bandwidth. All metrics currently
supported by graphite are now available to InfluxDB. I added in some
formatting functions, to handle integers and booleans as we know and
control their types, and the supporting regexes in the sanity checker.
Updating to InfluxDB 0.13.X started giving 400 errors due to the missing
Host header in HTTP/1.1 requests. HttpRequest has been updated to auto-
magically add the host and port to these requests if not explicitly
stated by the client code.
The exception code has been cleaned up to break out of the function
early if such a condition is raised, this avoids unnecessarily executing
code which will ultimately fail.

Fixes a couple issues to do with line formatting of influx DB data points. All
keys and values need commas and white space escaping. Values are also checked
for type. If a numeric or scientific value is detected this is output as an
Influx floating point/scientific number. Booleans are detected and output in
a canonical format. All other values are strings, which have double quotes
escaped and the entire string is wrapped in double quotes. The handling of
thresholds has changed before this becomes officially released. These values
if available are passed to the accumulation function in a dictionary, said
dictionary builds a single data point with multiple fields, rather than the
existing 5 data points, thus saving bandwidth costs.
