Add files required for docker setup

This commit adds all files that are required to run formhub in docker.
You can build the docker image using

`docker build -t formhub:latest .`

And run it with

`docker run -d -p 8000:8000 --name formhub formhub:latest`

and finally enter the container with

`docker exec -ti <container id> bash`

This is useful when you "sign up" and want to set the `is_active`
boolean on the user account so that you can log in (as the database is
inside the container)

+# PostgreSQL Client Authentication Configuration File
+# ===================================================
+#
+# Refer to the "Client Authentication" section in the PostgreSQL
+# documentation for a complete description of this file.  A short
+# synopsis follows.
+#
+# This file controls: which hosts are allowed to connect, how clients
+# are authenticated, which PostgreSQL user names they can use, which
+# databases they can access.  Records take one of these forms:
+#
+# local      DATABASE  USER  METHOD  [OPTIONS]
+# host       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostssl    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostnossl  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+#
+# (The uppercase items must be replaced by actual values.)
+#
+# The first field is the connection type: "local" is a Unix-domain
+# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
+# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
+# plain TCP/IP socket.
+#
+# DATABASE can be "all", "sameuser", "samerole", "replication", a
+# database name, or a comma-separated list thereof. The "all"
+# keyword does not match "replication". Access to replication
+# must be enabled in a separate record (see example below).
+#
+# USER can be "all", a user name, a group name prefixed with "+", or a
+# comma-separated list thereof.  In both the DATABASE and USER fields
+# you can also write a file name prefixed with "@" to include names
+# from a separate file.
+#
+# ADDRESS specifies the set of hosts the record matches.  It can be a
+# host name, or it is made up of an IP address and a CIDR mask that is
+# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
+# specifies the number of significant bits in the mask.  A host name
+# that starts with a dot (.) matches a suffix of the actual host name.
+# Alternatively, you can write an IP address and netmask in separate
+# columns to specify the set of hosts.  Instead of a CIDR-address, you
+# can write "samehost" to match any of the server's own IP addresses,
+# or "samenet" to match any address in any subnet that the server is
+# directly connected to.
+#
+# METHOD can be "trust", "reject", "md5", "password", "gss", "sspi",
+# "krb5", "ident", "peer", "pam", "ldap", "radius" or "cert".  Note that
+# "password" sends passwords in clear text; "md5" is preferred since
+# it sends encrypted passwords.
+#
+# OPTIONS are a set of options for the authentication in the format
+# NAME=VALUE.  The available options depend on the different
+# authentication methods -- refer to the "Client Authentication"
+# section in the documentation for a list of which options are
+# available for which authentication methods.
+#
+# Database and user names containing spaces, commas, quotes and other
+# special characters must be quoted.  Quoting one of the keywords
+# "all", "sameuser", "samerole" or "replication" makes the name lose
+# its special character, and just match a database or username with
+# that name.
+#
+# This file is read on server startup and when the postmaster receives
+# a SIGHUP signal.  If you edit the file on a running system, you have
+# to SIGHUP the postmaster for the changes to take effect.  You can
+# use "pg_ctl reload" to do that.
+
+# Put your actual configuration here
+# ----------------------------------
+#
+# If you want to allow non-local connections, you need to add more
+# "host" records.  In that case you will also need to make PostgreSQL
+# listen on a non-local interface via the listen_addresses
+# configuration parameter, or via the -i or -h command line switches.
+
+
+
+
+# DO NOT DISABLE!
+# If you change this first entry you will need to make sure that the
+# database superuser can access the database using some other method.
+# Noninteractive access to all databases is required during automatic
+# maintenance (custom daily cronjobs, replication, and similar tasks).
+#
