This patch introduces CAP_INTEGRITY_ADMIN, a new capability that allows
to setup IMA (Integrity Measurement Architecture) policies per container
for non-root users.

Why not use CAP_MAC_ADMIN? IMA is a mandatory policy. The scope
is system security administration. It seems to fit your needs.
I introduced CAP_MAC_ADMIN for Smack, and believe that IMA using
it would be completely appropriate.

Fine by me. I suppose we could be reusing it later on also for setting file extended attributes for IMA?

Yes. That would be completely consistent with the intention and the
Smack implementation.
