Is this a BUG REPORT or FEATURE REQUEST?:
/kind bug

What happened:
When trying to set a param for a semver version, ks param set returns an error for strconv.ParseFloat invalid float. Looks like the regex pattern for float matches repeated periods ((\.[0-9]+)*).
When trying with the --as-string flag, same error is thrown. It looks like the asString flag is not preserved in the EnvParamSet.

ERROR set params: strconv.ParseFloat: parsing "0.0.1": invalid syntax

What you expected to happen:
Set param correctly as string

How to reproduce it (as minimally and precisely as possible):
ks param set <component> <param> 0.0.1
ks param set <component> <param> 0.0.1 --as-string

Anything else we need to know?:
Regression in 0.10.1, works in 0.10.0.

Environment:

• ksonnet version (use ks version): 0.10.1
• Kubernetes version (use kubectl version): 1.9.4
