DeprecationWarning over invalid escape sequences

elasticsearch-py version (elasticsearch.__versionstr__): master branch

Description of the problem including expected versus actual behavior:

DeprecationWarning over invalid escape sequences. Escaping them or using raw string literals is preferred.

Steps to reproduce:

find . -iname '*.py' | xargs -P 4 -I{} python3.8 -Wall -m py_compile {}

./elasticsearch-py/test_elasticsearch/test_connection.py:330: DeprecationWarning: invalid escape sequence \?
  "^GET http://localhost:9200/\?param=42 \[status:500 request:0.[0-9]{3}s\]",
./elasticsearch-py/test_elasticsearch/test_connection.py:356: DeprecationWarning: invalid escape sequence \[
  '#\[200\] \(0.[0-9]{3}s\)\n#\{\n#  "answer": "that\\\\u0027s it!"\n#\}',
./elasticsearch-py/test_elasticsearch/test_connection.py:365: DeprecationWarning: invalid escape sequence \?
  "GET http://localhost:9200/\?param=42 \[status:200 request:0.[0-9]{3}s\]",

Thanks @sethmlarson, I wasn’t sure if 3.8 deprecated or just produced a deprecation warning for a future release.
