Convert integer style parameters to integer values
Convert integer style parameters to integer values

python-blazarclient sends all request parameters in the request body as
strings even though the blazar service only accepts integer values for
some parameters.

For instance, the instance reservation feature accepts an integer for
the 'vcpus' parameter, but the blazar client sends a string value for
the parameter with the --reservation vcpus=1 option.

This patch enables the --reservation option to convert integer style
parameters to integer values.
