use before/after for sorting processors

[ssoroka]

Feature Request

using order for numbering processors has some drawbacks. specifically inserting something into the list requires renumbering all other processors. This is especially difficult when the config comes from multiple files or places, for example writing configuration programmatically.

example use

[inputs.cpu]
[processors.rename]
  alias = "my_rename"
  before = "starlark"
[processors.starlark]
  after = "my_rename"
  before = "starlarkfoo"
[processors.starlark]
  alias = "starlarkfoo"
  after = "my_rename"
[outputs.file]

Current behavior:

uses ordering numbers

Desired behavior:

infer ordering from before/after field config
