CLI should allow for reasonable defaults

[richardtallent-erm]

First time using this tool, and I find it frustrating that so many command-line options are required. Most should have reasonable defaults, or be auto-detected. I just spent 10 minutes looking at a the [INFO] Scan manifest file... with no indicator of progress, finally hit Enter and got:

##[error]Encountered an error while generating the manifest.
##[error]Error details: Unable to generate a package version based on provided parameters. Please provide the package version in the 'PackageVersion' parameter.

@daneshbadlani , what are your thoughts on this request?

+1 for this one. trivy and syft have much easier entrypoint for generating sbom Any idea why sbom-tool requires all these arguments when competing tools dont?

[edgarrs]

@daneshbadlani will come up with a proposal for default values

[daneshbadlani]

Provided the default values to @aasim

Not easily actionable for current team without suggested defaults. A contribution with reasonable suggested defaults would be considered. Currently this work is not planned.

Looks like @daneshbadlani contributed some reasonable suggested defaults, did those get lost in the shuffle?
