Add Shutdown Delay Seconds to the sdk-client-test containers

[igooch]

What type of PR is this?

/kind feature

What this PR does / Why we need it:

Adds dynamic shutdown delay and graceful termination delay to the sdk-client-test. The will allow the user to dynamically set delays when creating a game server without needing to rebuild the container. These delays are important for preventing Game Servers from churning too quickly on a running cluster.

This will not affect the current conformance test that uses this test as the defaults are 0 for both delays.

Which issue(s) this PR fixes:

Working on #3795
