The travis CI builds failure

[z103cb]

Reverting changes to image push out of the build.
Fixes #487

I assumed that Image push not applicable in case of other than release.
@z103cb Probably we can fix this with condition of release branch to avoid image push incase of release

'if [ "$TRAVIS_PULL_REQUEST" = "false" && "$TRAVIS_BRANCH" != v*]; then make push-images; fi'

'if [ "$TRAVIS_PULL_REQUEST" = "false" && "$TRAVIS_BRANCH" == v*]; then make push-images; fi' or 'if [ "$TRAVIS_PULL_REQUEST" = "false" && "$TRAVIS_BRANCH" =~ ^v[0-9]\.[0-9]+\.[0-9]+ ]; then make push-images; fi' 

@Srihari1192 thanks for the suggestion, I will amend this PR.

Thanks ..Probably we need to test this before merge.. Just correction for above my suggestion it should be not equal to "$TRAVIS_BRANCH" != v*
