Dependency on gax not properly defined

[hiranya911]

It seems Firestore client has a dependency on gax that is not properly defined. I get the following error when adding only Firestore to my project:

I have the following in my pom.xml as per https://firebase.google.com/docs/firestore/quickstart

        <dependency>
            <groupId>com.google.cloud</groupId>
            <artifactId>google-cloud-firestore</artifactId>
            <version>0.25.0-beta</version>
        </dependency>

I had to also add the following to get past the error:

       <dependency>
            <groupId>com.google.api</groupId>
            <artifactId>gax</artifactId>
            <version>1.8.1</version>
        </dependency>

@hiranya911 : is this a duplicate of #2496 ?

Correct. I believe we can close this. Thanks @jabubake
