Subject: [PATCH] Import firestore conformance tests from
 googleapis/conformance-tests@32fd66cf7dffe8431643f08b5944108ac10c8bc2

* Add new script generate-conformance-tests.sh that can reliably update
  the various files that make up the conformance tests.
  * Currently the script only updates firestore tests.
  * Updating of the git-submodule linking to conformance-tests is not
    done by the script, it is expected that the developer will do the
    bumping.
* import proto definition
* generate updated TestDefinition from definition
* Add individual test files
* Add maven profile `gen-conformance-protos` that can be used to generate protos in `com.google.cloud:google-cloud-conformance-tests`

+# Google cloud conformance tests
+This maven module is intended to function as a central location for integration with
+[googleapis/conformance-tests](https://github.com/googleapis/conformance-tests).
+
+In this directory `conformance-tests` which is a git-submodule, containing the reference for which
+the various conformance test resources are updated to. 
+
+## Updating conformance-tests
+
+#### Prerequisites
+
+Part of the process of updating the conformance tests involves running maven a maven build for 
+this module. Ensure that all parent modules have been installed locally so the build can run.
+```bash
+pushd cd ../../
+mvn -Dmaven.test.skip.exec=true install
+popd
+```
+
+#### Performing the update
+
+To update the conformance tests run the following commands from this module directory:
+```bash
+pushd conformance-tests
+git pull
+popd
+./generate-conformance-tests.sh
+git add .
+```
+
+If an error is encountered while generating the new resources please check the `generate.log`
+written to the working directory.
+
+
+## Test Suites
+
+### Firestore
+
+The conformance test suites for Firestore are located in the `com.google.cloud.conformance.firestore`
+package.
+
+#### Files
+
+There are a number of files that together define the format of the tests as well as the tests 
+themselves.
+
+* `src/main/java/com/google/cloud/conformance/firestore/v1/TestDefinition.java`
+  * The generated protobuf objects used to read the tests definitions
+* `src/main/proto/google/cloud/conformance/firestore/v1/tests.proto`
+  * The proto definition for the tests. `TestDefinition.java` is generated from this definition.
+* `src/main/resources/com/google/cloud/conformance/firestore/v1/*.json`
+  * Each files is a json serialized `TestFile` definition (defined in tests.proto).

In order to specify this behavior,\nthe update must use a fieldmask \"a.b.c\". However, fieldmasks are only used for\nconcrete values - transforms are separately encoded in a\nDocumentTransform_FieldTransform array.\n\nThis test exercises a bug found in python (https://github.com/googleapis/google-cloud-python/issues/7215)\nin which nested transforms ({\"a.c\": \"ServerTimestamp\"}) next to nested values\n({\"a.b\": 7}) incorrectly caused the fieldmask \"a\" to be set, which has the\neffect of wiping out all data in \"a\" other than what was specified in the\njson-like input.\n\nInstead, as this test specifies, transforms should not affect the fieldmask.",
