feat(corda): single v5 dockerfile

[jagpreetsinghsasan]

Is your feature request related to a problem? Please describe.
Currently, with the PR #3480 , we have 2 seperate docker images, one which runs till generation of CPI (step3) and the original docker image which runs till starting of the VNodes (step5).
The tests which are already included in the cacti codebase runs using the image which provides the already setup vNodes.
This task involves updating the test case so that it uses the image which setup the docker aio only till creation of CPIs and the rest is handeled via the test case itself

Acceptance Criteria

1. The above mentioned test case to be updated
2. Removal of /tools/docker/corda-all-in-one/corda-v5/cordapps-deployment folder and have this as the base image under /tools/docker/corda-all-in-one/corda-v5/ folder
