Feat: [s][c][t] Add xml resource plugin

[olblak]

Signed-off-by: Olblak me@olblak.com

Fix #371

This pullrequest is a second attempt after #336

This time I am leveraging https://github.com/beevik/etree library

It went smoothly, and after some testing, I didn't notify any major change done to the xml file after an update

Accept spec parameters are:

• file: Define the xml file to manipulate
• path: Specify the xml path query
• value: Specify the xml value

Test

To test this pull request, you can run the following commands:

cd pkg/plugins/resources/xml
go test

The path accept xpath query such as https://docs.python.org/3/library/xml.etree.elementtree.html#supported-xpath-syntax:w
Note that I didn't test all of them.

@jetersen I may have found an integrated solution

[olblak]

Combined with the autodiscovery feature introduced in "#763", we could automate pom.xml

[jetersen]

If you want we can easily test it on Jenkinsci/bom since manifests are generated

@hervelemeur If you have some time, I would appreciate your review on this PR as you are pretty good at catching things I don't see

[olblak]

Erf, I had some (small) suggestions indeed, too late.
