Drop support for Java 7 #3426
Description
Clients won't be able to fetch dependencies from Maven due to Java 7 not supporting TLS 1.2 by default
Sample failed CI build, note the "Received fatal alert: protocol_version" message:
[ERROR] Failed to execute goal on project proto-google-cloud-bigquerydatatransfer-v1:
Could not resolve dependencies for project com.google.api.grpc:proto-google-cloud-bigquerydatatransfer-v1:jar:0.18.1-SNAPSHOT:
Failed to collect dependencies at com.google.api.grpc:proto-google-common-protos:jar:1.12.0:
Failed to read artifact descriptor for com.google.api.grpc:proto-google-common-protos:jar:1.12.0:
Could not transfer artifact com.google.api.grpc:proto-google-common-protos:pom:1.12.0 from/to central (https://repo.maven.apache.org/maven2):
Received fatal alert: protocol_version -> [Help 1]
This will continue to break any CI builds that use Java 7, e.g. in google-cloud-java.
This can be mitigated by #3427, which will solve the dependency fetch issue, but still leaves open concerns that we are supported an outdated, potentially insecure version of Java.
Java 7 doesn't have public security updates any more, and it has been deprecated by Oracle.

But what about https://tonyyan.wordpress.com/2015/07/17/enabled-tls-1-2-and-tls-1-1-on-java-7/ ?

I've spent a couple days trying to apply fixes to enable TLS 1.2 on Java 7 without any luck, but if someone else can do it that would be great!

Also even if we enable TLS 1.2 on Java 7, users would have to do the same thing.

We should get sign-off from the DPE, LOL, and Java gRPC teams.

Apiary libraries have yet to turn down Java 5 support, so this issue won't be resolved for a long time. Closing for now.
