This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run

Like that we can have code that works on multiple Rails versions, and we
dont need to mix a new method on Kernel.
Also, this makes easier to have multiple versions.
For instance, before master was 4.2, which is not the case anymore, so
on the code we should check versions and not Environment variables
BUGFIX: User locale was used index data
BUGFIX: missing Norwegian fulltext config
FEATURE: store the text used to index stuff in fulltext (for diagnostics / in page search)
FEATURE: re-index posts when locale changes (in bg job)
FEATURE: allow reindexing by trucating post_search_data
Note: I removed japanese specific config cause it requires custom pg config,
happy to add it once our base docker config ships with it
