in addition to other e2e related open issue #619 and #486 there are few minor issues in e2e tests as specified by @danehans in one of the comments in PR review - #485 (review)

• e2e test should perform cleanup when getting timeout. after further investigation I've noticed the curl command doesn't define a timeout and therefore if the command doesn't work it will hang until the test fails, but will not perform a cleanup since the curl doesn't return an error.
  the fix to this issue should be straight forward by adding a timeout to the curl command.

• HF_TOKEN env var should be checked at the beginning of the test setup in order to fail fast in case it's not defined.
