HPE 3par - Unable to use small QoS Latency value (less than 1)

[Raghavendra Tilay]

Suppose QoS Latency is created with value as 0.1

cinder qos-list
+--------------------------------------+--------+----------+--------------------+
| ID | Name | Consumer | specs |
+--------------------------------------+--------+----------+--------------------+
| fdd424ae-0934-4016-9f33-ee43e8caebfb | qos_01 | back-end | {'latency': '0.1'} |
+--------------------------------------+--------+----------+--------------------+

Then during create volume, below error occurs:

ERROR cinder.volume.drivers.hpe.hpe_3par_common [None req-da3a6a66-09b7-4b66-91bd-cb15a9b5116e admin None]
Exception: invalid literal for int() with base 10: '0.1'

Code changes are required to support small QoS Latency values.
