Give the metadata to both Watch and Lease

[srz09]

I checked your code and you forgot to give the metadata to the Watch client

/* rpc#WatchClient */
watch() {
    return this.client.getConnection('Watch').then(cnx => cnx.client.watch());
}

Should be

/* rpc#WatchClient */
watch() {
    return this.client.getConnection('Watch').then(cnx => cnx.client.watch(cnx.metadata));
}

Same things for LeaseClient#leaseKeepAlive

Will do a PR as soon as the npm run build:proto command will work
