context.

Add `sessiontest.GenerateSigned` function which returns signed random token.
Clarify that `sessiontest.Generate` returns an unsigned token. Use these
functions to assert the correctness of `Sign` / `VerifySignature` methods.

There is a need to add session token to `eacl.Table` structure. To do this,
we need to replace `token.SessionToken` type to another package since `eacl`
package imports `token` one (potential cross-import).
Create `pkg/session` package and replace session token implementation to it.
Related API in `container` package is deprecated from now.
Additionally implement test generator of random session tokens.
