Previously the default channel was "current", but after discussion with
@coderanger on GH-6979, it seems like this was a poor design decision.
Instead, we should use the stable channel and allow users to opt-in to
prerelease versions.
Fixes GH-6979
Before this change, the detection of a non-existing path on the guest
machine was considered as an error and lead to interrupt the current vagrant
action. This was actually a mistake to do so, since the config checks
are performed before many other vagrant actions than `provision`.
The config.validate phase is also intended to primarily check the options
sanity, but it cannot be too strict with the guest state (which can easily
get "out of automatic control").
With this change, we still apply these checks (when possible), but only warn
about possible configuration problems. This way, the subsequent
statements will happen anyway (e.g. ansible commands will be
executed, vagrant machine will be destroyed, etc.)
At least for ansible 2.0.0.1 the command `ansible-galaxy --help` is inappropriate for testing if ansible is installed, as it yields an error:
```
vagrant@vagrant-ubuntu-trusty-64:~$ ansible-galaxy --help && echo "OK"
Usage: ansible-galaxy [delete|import|info|init|install|list|login|remove|search|setup] [--help] [options] ...
Options:
-h, --help show this help message and exit
-v, --verbose verbose mode (-vvv for more, -vvvv to enable connection
debugging)
--version show program's version number and exit
ERROR! Missing required action
```
In cd93721, I relied on a suprising combination of quotes to protect ssh
execution to strip the quoted path to the private key file.
Since any ssh command line argument can be passed via
`ANSIBLE_SSH_ARGS`, it is quite more readable and easy to rely on the
`-i` argument, which is not affected like `-o IdentityFile=...` and also
supports multiple occurences.

Finally fix#6671
Note that I decided to not squash both commits for better
documentation and traceability.
Surprisingly (to me at least), a simple quote enclosure was not enough
to fix the problem.
Caveat: the stringified ansible-playbook command logged in verbose mode
is wrongly formatted (no quotes are escaped).
Fix#6671
Like in the (remote) `ansible` provisioner, it is preferred to pass the
directory that contains the generated inventory file. This way, advanced
inventory usages can be achieved by adding more inventory files into the
same directory.
Related to #2103 and #6500

String and Symbol types are different when used as a Hash key. By
default the Vagrant machine names are set in Symbol format, but users
may write their `host_vars` entries with String keys. This is a very
simple way to ensure smooth experience, without having to coerce the
data types during the config validation (e.g. with a library like
Hashie, which is currently not in the Vagrant dependencies)
