schemeshard crash on concurrent alter-{ext,}subdomains

[ijon]

KIKIMR-21965

AlterExtSubDomain is issued by schemeshard's own "sys tablets migration".
Meaning adding new system tablets (SVP, SA etc) to the existing extsubdomains.
And it clashes with AlterSubDomain disguised as AlterExtSubDomain presumably issued by Console tablet.
