As discussed on #942 (comment)
I realized that it would be super usefull to be able to do a multiple query combined with versionfilter on the csv resource

This pullrequest allows the following manifest to work

sources:
    name: Test Version filter
    kind: csv 
    spec:
      files: 
        - pkg/plugins/resources/csv/testdata/data.csv
      query: ".[*].firstname"
      versionfilter:
        kind: regex
        pattern: "^Jo"

Example

#############################
# CSV MANIPULATION EXAMPLES #

SOURCES
=======

versionfilter
-------------
Searching for version matching pattern "^Jo"
✔ Value "John", found in file "/home/olblak/Projects/Updatecli/updatecli/pkg/plugins/resources/csv/testdata/data.csv", for key ".[*].firstname"'

default
-------
✔ Value "John", found in file "/home/olblak/Projects/Updatecli/updatecli/pkg/plugins/resources/csv/testdata/data.csv", for key ".[0].firstname"'

Test

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

Additional Information

Tradeoff

Similar to the Json approach, I am deprecating the parameter multiple in favor of query

Potential improvement
