pgAdmin 4 commit: Added support for qtIdent, qtTypeIdent, qtLiteral for

Added support for qtIdent, qtTypeIdent, qtLiteral for quoting the
inputs.

In order to do the proper quoting around the identifier, different type,
and literal, we introduced respective functions qtIdent, qtTypeIdent,
qtLiteral in psycopg2 driver. Also, introduced them as the Jinja's
custom filter for using it directly inside the templates.

Also, created an utility - generate_keywords.py in order to generate
keyword lists from the latest PostgreSQL installation.
