Bigtable: Move admin api into its own artifact. (#3494)

The target usecases are different enough that the clients should be split.
Also, it avoids confusion associated with duplicate static names.

+### Testing code that uses Bigtable Admin
+
+Bigtable Admin integration tests are run against a real Bigtable instance.
+
+To run the tests:
+1. Set up the target table using `google-cloud-bigtable/scripts/setup-test-table.sh`
+2. Download the [JSON service account credentials file][create-service-account] from the Google
+   Developer's Console.
+3. Set the environment variable `GOOGLE_APPLICATION_CREDENTIALS` to the path of the credentials file
+4. Set the system property `bigtable.instance` to the full instance name you
+    created earlier. Example:
+    ```shell
+    mvn verify -am -pl google-cloud-bigtable-admin \
+      -Dbigtable.instance=projects/my-project/instances/my-instance

+## Quickstart
+
+[//]: # ({x-version-update-start:google-cloud-bigtable-admin:released})
+If you are using Maven, add this to your pom.xml file
+```xml
+<dependency>
+  <groupId>com.google.cloud</groupId>
+  <artifactId>google-cloud-bigtable-admin</artifactId>
+  <version>0.55.1-alpha</version>
+</dependency>
+```
+If you are using Gradle, add this to your dependencies
+```Groovy
+compile 'com.google.cloud:google-cloud-bigtable-admin:0.55.1-alpha'
+```
+If you are using SBT, add this to your dependencies
+```Scala
+libraryDependencies += "com.google.cloud" % "google-cloud-bigtable-admin" % "0.55.1-alpha"
+```

+## Authentication
+
+See the
+[Authentication](https://github.com/GoogleCloudPlatform/google-cloud-java#authentication)
+section in the base directory's README.
+
+## About Cloud Bigtable Admin
+
+[Cloud Bigtable][cloud-bigtable] is Google's NoSQL Big Data database service. It's 
+the same database that powers many core Google services, including Search, Analytics, Maps, and
+Gmail. The API is split into the data api and the admin api. This client targets the admin api.
+
+Be sure to activate the Cloud Bigtable Admin API on the Developer's Console to use Cloud Bigtable
+from your project.
+
+See the [Bigtable Amin client lib docs][bigtable-admin-client-lib-docs] to learn how to
+interact with Cloud Bigtable Admin API using this Client Library.
+
+## Getting Started
+#### Prerequisites
+For this tutorial, you will need a
+[Google Developers Console](https://console.developers.google.com/) project with the Cloud Bigtable 
+API enabled. You will need to 
+[enable billing](https://support.google.com/cloud/answer/6158867?hl=en) to use Google Cloud Bigtable.
+[Follow these instructions](https://cloud.google.com/docs/authentication#preparation) to get your
+project set up. You will also need to set up the local development environment by [installing the
+Google Cloud SDK](https://cloud.google.com/sdk/) and running the following commands in command line:
+`gcloud auth login`.
+
+#### Calling Cloud Bigtable
+
+The Cloud Bigtable API is split into 2 parts: Data API, Instance Admin API and Table Admin API.
+
+Here is a code snippet showing simple usage of the Table API. Add the following imports
+at the top of your file:
+
+
+```java
+import com.google.bigtable.admin.v2.ColumnFamily;
+import com.google.bigtable.admin.v2.InstanceName;
+import com.google.cloud.bigtable.admin.v2.BigtableTableAdminClient;
+```
+
+Then, to create a table, use the following code:
+```java
+InstanceName instanceName = InstanceName.of("my-project", "my-instance");
+
+TableAdminClient tableAdminClient = TableAdminClient.create(instanceName);
+
+try {
+    CreateTable createTableReq = TableAdminRequests.createTable("tableId")
+      .addFamily("cf2", GCRULES.maxVersions(10));
+    client.createTable(createTableReq);
+
+} finally {
+  tableAdminClient.close();
+}
+```
+
+## Troubleshooting
+
+To get help, follow the instructions in the [shared Troubleshooting
+document](https://github.com/GoogleCloudPlatform/gcloud-common/blob/master/troubleshooting/readme.md#troubleshooting).
+
+Transport
+---------
+Bigtable uses gRPC for the transport layer.
