Update Ansible to 2.6.14

[emkll]

From Github Dependency Graph notification:

Any version prior to 2.6.14 is vulnerable to CVE-2019-3828:

[...] path traversal vulnerability which allows copying and overwriting files outside of the specified destination in the local ansible controller host, by not restricting an absolute path.

All servers the Admin workstation should be connected to are trusted, and Admin workstations should not contain information other than what's running on the servers. To ensure defense-in-depth and resolve alerting noise, we should update this dependency.
