fix the issue with local file

[fsadykov]

Hello team,

This terraform module is using local_file. and every time when it's re-deploying module is creating new file. Please fix this problem terraform should create all those cache files inside .terraform

Example

module.jenkins_deploy.local_file.deployment_values: Creation complete after 0s (ID: 1c62ca38a9eca2ccc5e1be47cfe265d5d0562cc0)
module.external-dns.local_file.deployment_values: Creation complete after 0s (ID: 709c63a919ddd1ed06e294e94d5f6a5327f74ea5)
module.grafana_deploy.local_file.deployment_values: Creation complete after 0s (ID: 14b4649a6602641c5246ec79888eaa13de5d3986)
