Wildcard to operation name on sampling.strategies-file

[jdamasceno]

Proposal - what do you suggest to solve the problem or improve the existing situation?

Hi, i would like to request a feature to use a wildcard on the operation name in sampling.strategies-file of the jaeger collector.

Today:

    "operation_strategies": [
        {
          "operation": "op1",
          "type": "probabilistic",
          "param": 0.2
        },
        {
          "operation": "op2",
          "type": "probabilistic",
          "param": 0.2
        }
      ]

After the feature:

    "operation_strategies": [
        {
          "operation": "op*",
          "type": "probabilistic",
          "param": 0.2
        }
      ]

If you want a default, the config has a separate section for it. However, understanding a wildcard requires significant changes in how clients are implemented, across all languages.
