V3 specs not independent from each other (Deployment and cancelling deployment)

[renelehmann]

Issue

Tests for "deployments" and "v3" features includes creating and removing of a zip file (staticfile.zip).
If the zip file already/still exists an error on creating the zip file will occur:
"file already exists: assets/staticfile.zip"

Context

cats version: 7.4.0 (against cloudfoundry v19.0.0)
cats.json inlcudes v3 and deployments
running testsuite in parallel (-nodes=x) and without randomize.

The spec "Deployment" and "cancelling deployments" does/could interfere each other on having the same zip file name
which will be created on the "BeforeEach" and removed on the "AfterEach" step.
https://github.com/cloudfoundry/cf-acceptance-tests/blob/v7.4.0/v3/deployment.go.

error on (by creating the zip file if its already/still exists):

cf-acceptance-tests/v3/deployment.go

Expect(err).NotTo(HaveOccurred())

Possible Fix

Creating dedicated/independent zip filenames for each spec or else.

workaround:

• Running cats testsuite with "randomizeAllSpecs" will probably help to prevent the situation on interfere of each other but without a guarantee.
• Running cats testsuite without parallelize (default -node=1).
