docker: Add postgres docker build with full text search.

Browse Source 
This is multi-stage build which first builds tsearch-extras with the
current version of postgres and then configs postgres for zulip. The
zulip config installs the hunspell dictionaries, stop words file,
tsearch-extras, and creates the initial database.

**Testing Plan:**
1) `docker-compose up` the existing config.
2) Build the new image
3) Edit docker-compose.yml to use the new image id
4) `docker-compose up` and verify full text search is still working.

# To build run `docker build -f Dockerfile-postgresql .` from the root of the

# Install build tools and build tsearch_extras for the current postgres
# version. Currently the postgres images do not support automatic upgrading of
# the on-disk data in volumes. So the base image can not currently be upgraded
# without users needing a manual pgdump and restore.
