`INFO` seems to be throwing error against `master` branch of `RedisTimeSeries`

[dpipemazo]

Just upgraded RedisTimeSeries to commit e8030d14e7b8e186518b1b551cfa3cde261bf3c3 and am now seeing this when calling client.info() with redistimeseries-py:

    data = self._mclient.info(key)
  File "/opt/venv/lib/python3.7/site-packages/redistimeseries/client.py", line 301, in info
    return self.execute_command(self.INFO_CMD, key)
  File "/opt/venv/lib/python3.7/site-packages/redis-3.4.1-py3.7.egg/redis/client.py", line 901, in execute_command
  File "/opt/venv/lib/python3.7/site-packages/redis-3.4.1-py3.7.egg/redis/client.py", line 921, in parse_response
  File "/opt/venv/lib/python3.7/site-packages/redistimeseries/client.py", line 29, in __init__
    self.maxSamplesPerChunk = response['maxSamplesPerChunk']
KeyError: 'maxSamplesPerChunk'

Ran INFO on a key in my RedisTimeSeries and am now seeing this response:

Perhaps this response has changed? This was previously working OK against release 1.2.7

hi there @dpipemazo you're totally right ( the reply changed ) and this issue should be fixed by #59. The fix will be backwards compatible, so it should work both on 1.2 and 1.4 :)

Hi there @dpipemazo this fixed has been merged on #59 and tested for both v1.2 and v1.4. Closing the issue and thank you for the fast report :)

Thanks for the fix! Verified on my end, apologies for the late feedback.
