Duplicate farm names

If you configure farm with the same name more than once, there’s still only one farm with the given name and it’s properties are merged:

each property except web-app list is overridden by later definition
web-app lists are merged as hashmaps:
- merged web-app list does not contain duplicates
- override properties of web-apps with the same name are also merged as hashmaps

Example:

farms {
  farm 'A', {
    httpPort = 8081
    webapp ':ProjectA'
    webapp ':ProjectB', contextPath: '/aaa', inplace: false
  }
  farm 'A', {
    httpPort = 8082
    webapp ':ProjectB', contextPath: '/bbb'
    webapp ':ProjectC'
  }
}

As the result, farm "A" gets port=8082 and refers three web-apps:

webapp ':ProjectA'
webapp ':ProjectB', contextPath: '/bbb', inplace: false
webapp ':ProjectC'

Tip	Farms are strictly project-specific. If you define farms with the same name in two different projects, they are totally unrelated and are never merged.
