1.8.0

Add `utils_describe_stacks` data source. Update `atmos`. Add tests @aknysh (#281)

what

• Add utils_describe_stacks data source
• Update atmos
• Add tests

why

• The utils_describe_stacks data source has the same functionality as the Atmos CLI command atmos describe stacks, and accepts all the parameters that the CLI command accepts, see https://atmos.tools/cli/commands/describe/stacks
• The utils_describe_stacks data source will be used in Terraform to get configurations for stacks and components in the stacks

Terraform examples
