centos65: python daemons are throwing exceptions

[Raj Reddy]

following is for contrail-api, but the same happens on contrail-analytics-api.. seems like some issue in sandesh code generation for rate limiting..

Traceback (most recent call last):
  File "/usr/bin/contrail-api", line 9, in <module>

With python2.6 collections.deque does not support maxlen attribute
So we inherit the collections.deque and add a property maxlen to
make it work in 2.6 We use property and not a instance variable
maxlen because 2.7 has maxlen as a readonly property
Closes-Bug: #1500532
