Poor work with plugin_dir and index_token_filter

[sanikolaev]

If a table has non-empty index_token_filter, and is loaded with absent common section in the config, or absent plugin_dir param, daemon issue no messages about it (i.e. everything looks 'healthy').

According to the docs, plugin_dir has a default value:

The default path is /usr/local/lib/manticore/

Altering with any string is possible, btw. So, you can create table, insert data, and then say alter table t index_token_filter = 'bla';

As discussed with Alexey, it makes sense to think about the proper behaviour when you have different tokenization settings in different chunks in general.
