It is sometimes usefull for force reinstallation of the node_exporter,
for example during upgrade or if something is wrong with the current
installation.
This patch adds a --force command line option.
If the --force is given to the node_expoerter_install, it will reinstall
node_exporter to the latest version, regardless if it was already
installed.
The symbolic link in /usr/bin/node_exporter will be set to the installed
version, so if there are other installed version, they will remain.
Examples:
$ sudo ./dist/common/scripts/node_exporter_install
node_exporter already installed, you can use `--force` to force reinstallation
$ sudo ./dist/common/scripts/node_exporter_install --force
node_exporter already installed, reinstalling
