New component: Replace a label value based on regexp

[Dhivya247]

The purpose and use-cases of the new component

In Metrics transform Processor, request to create a component to replace dimension/label value based on regexp.
Currently we are reducing cardinality of a metrics by aggregating it based on regexp.
eg : - replace_all_matches(attributes, "/user//list/", "/user/{userId}/list/{listId}")

Similar to this do we have an option to replace/update the label/dimension values.
Value Actions take input only as a string not as regexp in Metrics transform processors

Example configuration for the component

        value_actions:
          - match_type: regexp
          - value: "^.*$"
          - new_value: ".*?(?=/)"

Telemetry data types supported

Is this a vendor-specific component?

• This is a vendor-specific component
• If this is a vendor-specific component, I am proposing to contribute and support it as a representative of the vendor.
