feat: supporting scanning go.mod

[xieshenzh]

Support scanning dependency vulnerabilities in go.mod.

@zvigrinberg @ilan-pinto please review this PR.
I disabled the CI validations for a few versions of IntelliJ, because the version of the go-plugin dependency is not compatible with these versions of IntelliJ.
After the alpha or preview release, we should not keep long term support of the plugin (i.e. supporting all the IntelliJ versions since 2021.1), because it is not common practice for IntelliJ plugins.

Hi @xieshenzh
The technical and code part of the PR looks good and off course i'll approve it, but before that, please clarify something - does the go-plugin that you're relying on , is compatible with other/newer versions ( not including IC community editions) of intelli-j since 2021.1 , excluding?

Hi @zvigrinberg , This plugin also has the go-plugin dependency, and it is compatible with IntelliJ 2021.3+.

So the RHDA plugin should be compatible with IntelliJ 2021.1+.
But when building the plugin, the go-plugin dependency can only be built with IntelliJ 2021.1. That's why I had to disable some github actions.

I think we should make a nightly release once this PR is merged. With that, we could verify if the compatibility works as expected.

@xieshenzh As discussed, first let's release it as snapshot ( "nightly channel")
