Disable MockTelemetryPlugin by default for integ tests

[mch2]

Description

With this plugin enabled I see significant increase in memory usage during ITs. This is due to a static map that collects Span entries per write/replication request and is not cleared until after the test execution. Tests with higher counts of independent writes are at risk of running oom or experiencing slow down / warnings related to this.

I've run two reported flaky tests on repeat with this disabled #12801 and #12836 and do not see failures.

Disabled the plugin by default until this is resolved given it is still under FeatureFlag.

Can we hold on this PR. I will try to fix within this week only. Otherwise we can go ahead with this PR.

I would prefer not to wait. This could incorrectly flag a lot of tests as flaky that would take more time to analyze. We can re-enable once the fix is ready.
