image name must not have leading or trailing whitespace

**What this PR does / why we need it**:
verifies that an image name can not have leading or trailing whitespace

**Which issue this PR fixes**
fixes #47490

**Special notes for your reviewer**:
i was surprised we had not caught this, so if there is an image spec that says leading and trailing whitespace is a good thing, i am open to correction.

i was made aware of downstream users of validate pod template spec that used " " as a special token.  as a result, i only do the validation of image name " " in the `Pod` only.
