Solves issue #341

Make protected-mode configurable for sentinel

Add type alias tests to data types

enable sentinel bind usage with multi ip

The dotdeb project has been discontinued and never published packages
for Debian 9 or 10. 645229f dropped
Debian 8 support so this is essentially dead code that can only lead to
problems.

Drop dotdeb repo management support

This moves package_ensure and minimum_version parameters to init.pp.
They don't make sense on the instance because they're not actually
honored. They are only used to determine whether protected mode is
supported. Having that variable in the main redis class allows the
sentinel to reuse the definition.

Move package parameters to init.pp

This avoids the need to declare a master.

modulesync 4.0.0

The path when using an SCL is non-standard. Using the correct one
prevents permission issues.

CentOS 6 is EOL and we can't test RHEL 6. That means there's no
guarantee it continues to work. Also, all other distros mentioned in
metadata.json run systemd. This allows the module to be cleaned up.

For the sentinel, every supported distro provides a systemd unit file as
part of the package. On Debian, it also provides a sysvinit file.
Including this in the module is not needed. In most cases, the systemd
unit file would have already shadowed the sysvinit file.

These default to true and by now we can rely on them to be present. The
systemd unit files all have them so there's really no reason to keep
this around.

This removes the use of file defaults and moves all variables used in
the template together.

Drop sysinit support

Add support for rename-command in redis.conf

Remove support for THP in Redis module - recommend forge module

Set the correct log dir on RH SCL

These are only used in a single file. This allows for a much shorter
definition.

0c851ce changed $log_dir for SCL
deployments. However, $log_file was still absolute. That caused it to
log to a non-existing directory.

This patch makes $log_file accept a relative path. If a relative path is
specified, $log_dir will be prepended. Absolute paths are still used
directly which keeps API compatibility.

Allow relative paths for $log_file

Make spec_helper.rb managed again

puppetlabs/stdlib: Allow 7.x

This avoids the need for deamon reload code, which will be dropped in
camptocamp/systemd 3.0.0.

This allows any service where the ulimit isn't in the service file to be
managed via a drop in.

Set ulimit via systemd using camptocamp/systemd

Correct config_dir for scl support

augeasproviders_core was already redundant since augeasproviders_sysctl
already depended on it and wasn't used directly.

Since augeasproviders_sysctl is only used in redis::administration, an
optional class, this reduces the installed size for most deployments.

Make augeasproviders_sysctl a soft dependency

Declare Puppet 7 support
