Simplify the default configuration file

After some discussion with the community it was decided to
clean the configuration file from excessive comments and
explicitly configured default values. Also, mod_mam and
mod_http_upload have been added.

The rationale for this is to have a clean and not bloated
configuration file which doesn't scare away newcomers and
which has all features from the Compliance Suite 2018 (XEP-0387)
enabled by default.

For further configuration an admin is encouraged to read the
documentation at https://docs.ejabberd.im/admin/configuration

###' LOGGING
##
## loglevel: Verbosity of log files generated by ejabberd.
## 0: No ejabberd log at all (not recommended)
## 1: Critical
## 2: Error
## 3: Warning
## 4: Info
## 5: Debug
##
loglevel: 4
##
## rotation: Describe how to rotate logs. Either size and/or date can trigger
## log rotation. Setting count to N keeps N rotated logs. Setting count to 0
## does not disable rotation, it instead rotates the file and keeps no previous
## versions around. Setting size to X rotate log when it reaches X bytes.
## To disable rotation set the size to 0 and the date to ""
## Date syntax is taken from the syntax newsyslog uses in newsyslog.conf.
## Some examples:
## $D0 rotate every night at midnight
## $D23 rotate every day at 23:00 hr
## $W0D23 rotate every week on Sunday at 23:00 hr
## $W5D16 rotate every week on Friday at 16:00 hr
## $M1D0 rotate on the first day of every month at midnight
## $M5D6 rotate on every 5th day of the month at 6:00 hr
##
log_rotate_size: 10485760
log_rotate_date: ""
log_rotate_count: 1
##
## overload protection: If you want to limit the number of messages per second
## allowed from error_logger, which is a good idea if you want to avoid a flood
## of messages when system is overloaded, you can set a limit.
## 100 is ejabberd's default.
log_rate_limit: 100
###. ===============
###' NODE PARAMETERS
##
## net_ticktime: Specifies net_kernel tick time in seconds. This options must have
## identical value on all nodes, and in most cases shouldn't be changed at all from
## default value.
##
## net_ticktime: 60
###. ================
###' SERVED HOSTNAMES
##
## hosts: Domains served by ejabberd.
## You can define one or several, for example:
## hosts:
## - "example.net"
## - "example.com"
## - "example.org"
##
hosts: hosts:
- "localhost" - "localhost"
## loglevel: 4
## route_subdomains: Delegate subdomains to other XMPP servers. log_rotate_size: 10485760
## For example, if this ejabberd serves example.org and you want log_rotate_date: ""
## to allow communication with an XMPP server called im.example.org. log_rotate_count: 1
## log_rate_limit: 100
## route_subdomains: s2s
###. ============ certfiles:
###' Certificates - "/etc/letsencrypt/live/*/*.pem"
## List all available PEM files containing certificates for your domains,
## chains of certificates or certificate keys. Full chains will be built
## automatically by ejabberd.
##
## certfiles:
## - "/etc/letsencrypt/live/example.org/*.pem"

## ca_file: "/etc/ssl/certs/ca-bundle.pem"

###' DATABASE SETUP
## ejabberd by default uses the internal Mnesia database,
## so you do not necessarily need this section.
## This section provides configuration examples in case

## Please consult the ejabberd Guide for details on database creation.
##
## MySQL server:
##
## sql_type: mysql
## sql_server: "server"
## sql_database: "database"
## sql_username: "username"

##
## sql_type: pgsql
## sql_server: "server"
## sql_database: "database"
## sql_username: "username"
## sql_password: "password"

## Number of connections to open to the database for each virtual host
##
## sql_pool_size: 10
##
## Interval to make a dummy SQL request to keep the connections to the
## database alive. Specify in seconds: for example 28800 means 8 hours
##
## sql_keepalive_interval: undefined
##
## Use the new SQL schema
##
## new_sql_schema: true
##
## A database can also can be used to store information from several
## modules. To enable storage to the database, just make sure it is
## setup above and set default_db: sql if you want to use SQL for
## all modules.

## rely solely on dialback if you want to federate with other servers,
## because a lot of servers have dialback disabled and instead rely on
## PKIX authentication. Make sure you have proper certificates installed
