[GOBBLIN-2247] Increase RPC retry budget to 10 min for Temporal gRPC throttling

[DaisyModi]

Dear Gobblin maintainers,

Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below!

JIRA

• My PR addresses the following Gobblin JIRA issues and references them in the PR title.
  • https://issues.apache.org/jira/browse/GOBBLIN-2247

Description

• Here are some details about my PR, including screenshots (if applicable):

Follow-up to #4176. The previous RPC retry defaults (initialInterval=500ms, maximumInterval=30s, maximumAttempts=10) provided ~2.5 minutes of cumulative retry budget — only marginally better than the Temporal SDK's built-in 1-minute expiration default (DefaultStubServiceOperationRpcRetryOptions). This was insufficient to survive sustained throttle bursts of up to 10 minutes observed in production.

Changes to default values in GobblinTemporalConfigurationKeys:

Parameter	Old	New	Rationale
initialInterval	500ms	1000ms	Less aggressive on a throttled server
maximumInterval	30s	60s	Sufficient spacing during sustained throttling
backoffCoefficient	2.0	2.0	Unchanged
maximumAttempts	10	15	Fewer attempts needed thanks to larger max interval

With initialInterval=1s, coefficient=2.0, maximumInterval=60s, maximumAttempts=15:

• Attempts 1–6: 1 + 2 + 4 + 8 + 16 + 32 = 63s (hits 60s cap at attempt 7)
• Attempts 7–15: 9 × 60s = 540s
• Total: ~603s (~10 min)

All values remain configurable via Typesafe Config.

Tests

• My PR adds the following unit tests OR does not need testing for this extremely good reason:

Config-only change — no logic changes. buildRpcRetryOptions is unchanged; only the default constants are tuned.

Commits

• My commits all reference JIRA issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "How to write a good git commit message".
