[ZEPPELIN-1876] smart psql autocomplition
### What is this PR for?
This PR changes autocompletion behaviour in postgresql interpeter.
There are some changes:
* [main change] autocompletion now depends on what are you typing. Now
there are four types of competion: schema, table, column and keywords. If you
typing new word then autocompetion suggests only keywords and schema names. If
you are typing after schema name with point then you get list of tables in that
schema. Also if you typing a name after point after a table name you will get a
list of column names of this table.
* autocomption now supports aliases in sql. If you write alias for a table
you will get a list of columns of an aliased table if you write down the alias
and a point.
* new option are availble for postgresql interpreter:
postgresql.completer.schema.filter. It allows filter schema names loaded into
autocompletion (no more garbage schema names).
* autocompletion now load keywords only in low case (otherwise there are so
many keywords in a list of autocompletion that it is becomes uncomfortable)
### What type of PR is it?
Improvement
### Todos
* [ ] - sort names in the output of autocompletion
* [ ] - list only schema names if we are typing a schema name (for example
after keywork FROM)
* [ ] - add description in autocompletion list for schema names - schema,
for table names - table and so
