feat: allow users to use version suffix pipeline runs

[rkpattnaik780]

What changes were proposed in this pull request?

Currently, when pipelines are created using elyra from the Notebooks, each additional iteration of the pipeline run creates a new pipeline version identified by timestamp.

The PR will allow user to switch from timestamp identifiers to versions numbers (v1, etc) using an environment variable KFP_SUFFIX_USE_VERSION. This will make the pipeline runs easily distinguishable.

Fixes #3182

@rkpattnaik780 overall LGTM, but could you mention the new env var in the docs

[lresende]

@rkpattnaik780 could you also rebase the pr to make sure all the tests are passing

[rkpattnaik780]

In an off-thread discussion, we noticed the current implementation will fail if:

• once we have few pipeline. ex: 10 , latest version will be -v10
• a user delete the 6th pipeline, the total_size=9
• the next call of pipeline, would try to create the version '-v10`
  again

We are trying to find a workaround for this issue. Cc @harshad16
