Fix microversion comparison approach in functional tests

Manila microversions have following template:

x.y

where 'x' and 'y' both digits.

And now manilaclient functional tests transform string 'x.y' to float,
but it is incorrect thing to do because float assumes that each
left value is bigger than right one. And it is not suitable
for microversion comparisons.

Examples:

Microversions true conditions:
2.9 < 2.10
2.9 < 2.81

Float true conditions:
2.9 > 2.10
2.9 > 2.81
