Dev improve rpm generation

[BraulioV]

Hi team,

in this PR I made a full rework of how the Wazuh packages for RPM based OS are made. Now, everything is built using a Docker image. This Docker image has installed all the necessary packages to compile Wazuh and build a .rpm package.

Also, I made a full rework of the scripts to build the RPM package. Now are more easy to use and easy to maintain. In addition, I add some new cool features. These are the most relevant:

• Added support for different directories: Now you can build rpm packages to be installed in different directories. For example: /opt/ossec. By default, the package will be built to be installed in /var/ossec.
• Added support to set the number of threads before building the package.
• Change the release of the package dynamically.

How to use them:

• Build a wazuh-manager package for x86_64: # ./generate_wazuh_rpm.sh -b v3.4.0 -t manager -a x86_64 -j 15 -r 2.
• Build a wazuh-agent package for i386: # ./generate_wazuh_debs.sh -b 3.4 -t agent -a i386.
• Build a wazuh-api package: # ./generate_wazuh_rpm.sh -b v3.4.0 -t api.

Available parameters:

# ./generate_wazuh_rpm.sh -h

Usage: ./generate_wazuh_rpm.sh [OPTIONS]

    -b, --branch <branch>     Select Git branch [master].
    -h, --help                Show this help.
    -t, --target              Target package to build: manager, api or agent.
    -a, --architecture        Target architecture of the package.
    -j, --jobs                Change number of parallel jobs.
    -l, --legacy              Build the package for CentOS 5.
    -r, --release             Package release.
    -p, --path                Installation path for the package.

Regards,
Braulio.

Great job!.

Please, create a folder for the temporary files:

/tmp/wazuh-builds/build-000000001

In this way, we can run several times the script.

Also, include in the output the package path.
