[brendonjwong]

Implemented the /sys/mounts/ endpoints in vault.sys.mounts. This should resolve https://github.com/amperity/vault-clj/issues/84.

All methods covered with integration tests.

🤔 this test passes for me locally

This is probably why the test is failing: https://github.com/amperity/vault-clj/blob/e52b1b2c83cf0ed7a0ec2cc2f14ba043fe6b7389/.circleci/config.yml#L19

😬 is there anything that prevents us from bumping that to latest?

[greglook]

No, we should be testing against the latest; most of the APIs are backwards-compatible, some things just won't be supported in the older versions (as you noticed). I've been testing against v1.11.3 locally.
