This PR adds the ability to execute the installation script non-interactively, useful for automated provisioning scripts such as Chef, Puppet, Ansible, Salt, etc.
Simply feed the environment variables into the install script to skip the prompts.
For debug and verification purposes, the script will still output the selected config variables.
The plus side is that the environment variables also support command substitution (see REDIS_EXECUTABLE).
```
sudo REDIS_PORT=1234 REDIS_CONFIG_FILE=/etc/redis/1234.conf REDIS_LOG_FILE=/var/log/redis_1234.log REDIS_DATA_DIR=/var/lib/redis/1234 REDIS_EXECUTABLE=`command -v redis-server` ./utils/install_server.sh

Sometimes Redis patch releases are released in a matter of weeks or days
one after the other. In order to have less release friction the idea is
to stop writing changelogs by hand, in order to also cover everything
interesting there is to say. Useless things can be deleted manually by
the changelog. Also this gives more credits to contributors since often
in the commit message involved people are cited even when they are not
the authors of the commit.
Once this is merged:
- merge the latest changes to commands.json in antirez/redis-doc
- re-run: utils/generate-command-help.rb > src/help.h
Then we'll have nice and easy tab-completed help in redis-cli again.
Closes#1909
This was discovered by _bodya and reported in the IRC channel.
Everything worked fine as these scripts are always executed as shell
scripts.
Closes#1728
The function to generate graphs is also more flexible as now includes
step and max value. The step of the samples generation function is no
longer limited to min step of 1000.
