/**
* Test that multiple concurrent tenant migrations are supported.
*
* Tenant migrations are not expected to be run on servers with ephemeralForTest, and in particular
* this test fails on ephemeralForTest because the donor has to wait for the write to set the
* migration state to "committed" and "aborted" to be majority committed but it cannot do that on
* ephemeralForTest.
*
* Incompatible with shard merge, which can't handle concurrent migrations.
*
* @tags: [
* incompatible_with_macos,
* incompatible_with_shard_merge,
* incompatible_with_windows_tls,
* requires_majority_read_concern,
* requires_persistence,
* serverless,
