[MTOOLCHAINS-38] Add skipToolchains parameter for ToolchainMojo

[jira-importer]

Jacky Chan opened MTOOLCHAINS-38 and commented

If you use Github actions actions/setup-java@v2 to setup Java env, java version and vendor are all defined well, and it's not necessary to active maven-tools-plugin. 

- uses: actions/setup-java@v2
  with:
    distribution: 'temurin'
    java-version: '11'

If you can not skip maven-tools-plugin, and you should create a ~/.m2/toolchains.xml file for CI.

Affects: 3.0.0

As you point out this is a CI configuration issue, and can be addressed in toolchains.xml.
