Fix Eventually timeout race condition in parallel test execution

Move SetDefaultEventuallyTimeout from individual Describe blocks to
BeforeSuite to fix timeout race condition.

Root cause: When tests run in parallel with `-p`, all test files execute
in the same process. SetDefaultEventuallyTimeout is global to Gomega, so
whichever Describe block runs last overwrites the timeout for all tests.

The sequence was:
1. func_deploy_test.go sets timeout to 10 minutes
2. metrics_test.go sets timeout to 2 minutes (120 seconds)
3. All subsequent tests use 2 minutes, causing deployment tests to timeout

Solution: Set timeout once globally in BeforeSuite before any Describe
blocks execute. This ensures a consistent 10 minute timeout for all tests.

Removed redundant timeout settings from:
- test/e2e/func_deploy_test.go (10 min)
- test/e2e/func_middleware_update_test.go (10 min)
- test/e2e/bundle_test.go (5 min)
- test/e2e/metrics_test.go (2 min - the culprit)
