generate-dashboard-configmap-yaml.sh : asterisk character in panel query is incorrectly evaluated

[ghost]

The script generate-dashboard-configmap-yaml.sh doesn't correctly export dashboard containing asterisk character in the query of panels.

This issue occurs also when the script generate-dashboard-configmap-yaml.sh is executed in a not-empty directory.

To reproduce this issue execute the following steps:

1. Create a dashboard containing a panel with the following metric "100 * 100"
2. Open a terminal session, verify that the current directory isn't empty
3. Execute the script generate-dashboard-configmap-yaml.sh in order to export the dashboard created in the step 1
4. Verify the yaml file containing the dashboard exported to a ConfigMap, the metrics "100 * 100" isn't present. The character "*" has been replaced with the file list of the current directory. This is a not expected behaviour
