We would like to make it easier to accept multiple annotations.
Examples:
```
country("GB") && annotation(...)
annotated(annotated(X,...),...)
```

This patch makes it easier to configure existing placement rules only with string.
1. placement(n) rule can be used to reuse earlier definitions
2 .&& can be used in addition to all(n1,n2)
3. country(c) accepts exclusions (like '!RU'), regions ('EU','EEA'), all and none
See the 'full example' unit test, which uses all of these, in a realistic example.

placement.AllowedCountry is the old way to specify placement, with the new approach we can use a more generic (dynamic method), which can check full node information instead of just the country code.
The 90% of this patch is just search and replace:
* we need to use NodeFilters instead of placement.AllowedCountry
* which means, we need an initialized PlacementRules available everywhere
* which means we need to configure the placement rules
The remaining 10% is the placement.go, where we introduced a new type of configuration (lightweight expression language) to define any kind of placement without code change.
