Fixing some tests

[voyvodov]

fixing templated testing policies

To allow writing under specific key we need to wildcard it (e.g. allow any
subkey)
Also, to work correctly root key must
also present (e.g. store/metadata/*)

Fixing SDB tests.

Templated tests needs approle to work (token doesn't contain metadata).
Also fixing --local test to provide vault token in minion file (as
it cannot get such from master during local run)

removing v 0.9.6 from tests

This version is very old and out of support years ago.
The oldest version currently supported is 1.8.x, so probably 1.3.x
should be removed too.

Add few fixes for the docs

[lkubb]

Thanks again for working on this! Some general comments since this touches many things:

The SDB tests can be fixed more simply: 27d9184 (they were just missing the master/minion config setup which broke after the migration)

The master_config stuff in the docstrings is intended to link to the corresponding Salt docs site, which can be made working via e670b3d. Just removing the :master_config: directive is a bandaid imho.

I am all for dropping the old Vault versions in the test suite, but think we should have one initial release with as few differences to current Salt as possible. There's more things I would like to get rid of since we're not bound to Salt core anymore.

You're right that tests for e.g. secret version deletion with templated policies would require more broad permissions, but there aren't any currently. That could be an area for improvement.

The test_sdb_runner should actually test the runner, not the execution module.

I see all the changes are already implemented correctly in #3
so no reason to keep this PR open too.
