field names with dots

[maja42]

It seems that the following regex is used to detect named references:

namedReference = regexp.MustCompile(`%{(\w+(?::\w+(?::\w+)?)?)}`)

This forbids field names with special characters like dots and dashes to be used. The pattern will not be detected and doesn't match - without any error message.

Especially the dot is important to stay compatible with frameworks like LogStash, whose grok-patterns heavily relies on dots within names to add some structure.

Example:

• pattern: %{DATA:var.with.dots}
• pattern definitions/regexes: `map[string]string{"DATA": "dat[0-9]"}
• input: "dat123"

@vjeantet I think this is solved already with a24cc6340a165eb29c803e84b95c3a39d591e201
