[MINOR][DOC] Use raw triple double quotes around docstrings where there are
occurrences of backslashes.
From [PEP 257](https://www.python.org/dev/peps/pep-0257/):
> For consistency, always use """triple double quotes""" around docstrings.
Use r"""raw triple double quotes""" if you use any backslashes in your
docstrings. For Unicode docstrings, use u"""Unicode triple-quoted strings""".
For example, this is what help (kafka_wordcount) shows:
```
DESCRIPTION
Counts words in UTF8 encoded, '
' delimited text received from the network every second.
Usage: kafka_wordcount.py <zk> <topic>
To run this on your local machine, you need to setup Kafka and create
a producer first, see
http://kafka.apache.org/documentation.html#quickstart
and then run the example
`$ bin/spark-submit --jars
external/kafka-assembly/target/scala-*/spark-streaming-kafka-assembly-*.jar
examples/src/main/python/streaming/kafka_wordcount.py localhost:2181
test`
```
This is what it shows, after the fix:
```
DESCRIPTION
Counts words in UTF8 encoded, '\n' delimited text received from the
network every second.

examples/src/main/python/streaming/kafka_wordcount.py \

```
The thing worth noticing is no linebreak here in the help.

Use raw triple double quotes around doctrings to escape backslashes.
From PEP 257:
For consistency, always use """triple double quotes""" around docstrings.
Use r"""raw triple double quotes""" if you use any backslashes in your
docstrings. For Unicode docstrings, use u"""Unicode triple-quoted strings""".
For example this is what help (kafka_wordcount) shows:
