Test attribute-based eACL for big objects

[carpawell]

Context

We did a huge work to make it real: nspcc-dev/neofs-api#283, nspcc-dev/neofs-node#2716. Basically: restrict some operation by some attribute, make this operation with the attribute and big payload, make sure it was accepted and every child part (that does not have any attributes) is also accepted.

Solution Example

1. Create a container with PUT available for OTHER roles and eACL flag should be set (the test should be able to set eACL tables)
2. Create and set eACL for this container that restricts PUT operations for OTHER role
3. Create a bearer token that allows OTHER role to PUT objects with test=test attribute and sign it
4. Create another wallet
5. Try to PUT big object with test=test attribute to the container using another wallet and attaching the bearer
6. Try to GET it (just to be sure that parts were accepted OK and are available)

5. should be OK since the bearer overwrites eACL rules for such objects.
