Subject: [PATCH] fix(instances): add missing TOOL_NAME variable to compose
 template

The compose template uses {{TOOL_NAME}} for container_name but
we weren't passing it in the variables dict, causing YAML parse error.

Error was:
yaml: cannot use 'map[string]interface {}{"TOOL_NAME":interface {}(nil)}' as a map key
