Because alpine uses musl instead of libc, the e2e/cypress was not compatible (#23602)

So:
- Created new VM based on debian-slim
- Could also be used as a build VM

Fixes:
- ginstall issue with merge somewhere.
- Trimmed down the alpine VM since we don't need the extra libraries for cypress

+# Using this docker image
+
+Currently tagged and uploaded to dockerhub as srclosson/integrations-ci-build 
+
+Based off of `circleci/node:12-browsers` 
+
+## User
+The user will be `circleci`
+The home directory will be `/home/circleci`
+
+## Node
+- node 12 is installed
+- yarn is installed globally
+- npm is installed globally
+
+## Go
+- Go 1.14 is installed in `/usr/local/bin/go`
+- golangci-lint 1.23.7 is installed in `/usr/local/bin/golangci-lint`
+- mage is installed in `/home/circleci/go/bin/mage`
+
+All of the above directories are in the path, so there is no need to specify fully qualified paths.
+
+## Grafana
+- Installed in `/home/circleci/src/grafana`
+- `yarn install` has been run
+
+## Integration/Release Testing
+There are 4 previous versions pre-downloaded to /usr/local/grafana. These versions are:
+1. 6.6.2
+2. 6.5.3
+3. 6.4.5
+4. 6.3.7
+
+To test, your CircleCI config will need a run section with something similar to the following
+```
+- run:
+        name: Setup Grafana (local install)
+        command: |
+          sudo dpkg -i /usr/local/grafana/deb/grafana_6.6.2_amd64.deb
+          sudo cp ci/grafana-test-env/custom.ini /usr/share/grafana/conf/custom.ini
+          sudo cp ci/grafana-test-env/custom.ini /etc/grafana/grafana.ini
+          sudo service grafana-server start
+          grafana-cli --version
+```
+
+
+# Building
+To build, cd to `<srcroot>/packages/grafana-toolkit/docker/grafana-plugin-ci`
+```
+./build.sh
+```
+
+# Developing/Testing
+To test, you should have docker-compose installed.
+```
+cd test
+./start.sh
+```
+
+You will be in /home/circleci/test with the buildscripts installed to the local directory.
+Do your edits/run tests. When saving, your edits will be available in the container immediately.
