Use podman as runtime to build and execute the UI

[rmarting]

Is your feature request related to a problem? Please describe.

docker is currently supported to build and run locally UI, however in development environments podman or buildah are the tools used to build and run containers.

If you don't have docker the build process fails with:

❯ make cbuild
docker build -t quay.io/konveyor/move2kube-ui-builder:latest --cache-from quay.io/konveyor/move2kube-ui-builder:latest --target build_base                             --build-arg VERSION=latest .
make: docker: No such file or directory
make: *** [Makefile:73: cbuild] Error 127

Describe the solution you'd like

Allow to build and run locally this tool using other container runtimes, such as podman.

Describe alternatives you've considered

Additional context

This feature will allow to increase the number of users/developers of this tool.

@rmarting The recommended solution seems to be just to alias docker to podman since podman is a drop in replacement for docker:

alias docker=podman

@HarikrishnanBalagopal it could help that using an alias, but IMHO the Makefile should cover both container technologies if we want to demostrate the value of other container runtimes such as podman.

Replacing docker references in the Makefile file to podman the build works successfully. Now it is not running because it is affected by the issue reported here.

Maybe the solution could add some container runtime check at the begining of the Makefile to avoid the developer has to use alias or change the development station to build and compile this tool. Again this mi opinion, and maybe I am wrong, and the tool has to force to use docker to build and run.

WDYT?

@HarikrishnanBalagopal I am not an expert developer in Makefile files, however I created this PR #98 as an approach of my idea to use docker or podman to build and run the tool. I hope this PR could help to improve this User Experience.

Open to modify or adapt the file with the rules or recomendations you could suggest me.
