Add Example for sending information to DB via UDP

[shantanoo-desai]

Due to lack of documentation for UDP, this example
provides basic usage of sending information points
via UDP. The code structure followed is similar, if
not same as other examples in the examples directory.

Locally tested with:
InfluxDB v1.6.1 on Windows10 and influxdb-python v5.0.0
and should not break anything

Things To do

• Update Documentation

This PR addresses #646 #647

@aviau Any suggestions on how to overcome the failed tests?

[aviau]

It looks like travis's pypy plugin is broken. I would probably merge a PR that disables pypy for now.

[shantanoo-desai]

Should I change the .travis.yml file or will this be done by someone else?

[aviau]

Yes, someone should do it.

That would be in a separate pull request.

@nevmerzhitsky @aviau @xginn8 Travis tests have passed on the documentations. I however want to address that during the tox -e docs I came across three warnings, where the docstring one core file (client.py) has some linting errors.
And also a Warning html_static_path entry error which stems from docs/sources/conf.py.

I have already resolved the Issue and wanted to know if this should be on a different PR or should I push the code here?

[shantanoo-desai]

@xginn8 The changes you requested were already addressed in the PR. The ports for UDP is 8089 which is by default and also according to the Docs. Everything else in the code is in accordance with the other examples.

@shantanoo-desai I think it makes more sense to pass the UDP port as an arg, rather than the TCP port used to connect to InfluxDB. You can omit the hostname and TCP port altogether if you want to make it more clear.

Also, please push any other fixes unrelated to this example in a separate PR.

[shantanoo-desai]

@xginn8 As mentioned, I have improved the tutorial_udp.py file. All tests have passed. I mentioned the changes where I pass udp_port information as Argument for the example.

thanks for contributing @shantanoo-desai!!

Too bad this part of the updated docs seems not to have been integrated into the online doc : https://influxdb-python.readthedocs.io/en/latest/examples.html

[shantanoo-desai]

@xginn8 Is there something I need to do to show this example on the Docs? I think I executed all necessary steps in the PR for Sphinx

[xginn8]

@shantanoo-desai I'll take a look as to why it hasn't updated yet, thanks for the tip
