Setting the keepalive option before opening up the paramiko session
in order to avoid the slim chance that the connection is stalled
in the short time between opening the session and setting up the
keepalive. I described the issue I am solving at

'_', they will be loaded after non prefixed modules are checked they can
be full modules or symlinks to existing ones (alias)
also updated ansible doc to ignore these, will eventually add selective
display
There is a common pattern in modules where some parameters are required
only if another parameter is present AND set to a particular value. For
instance, if a cloud server state is "present" it's important to
indicate the image to be used, but if it's "absent", the image that was
used to launch it is not necessary. Provide a check that takes as an
input a list of 3-element tuples containing parameter to depend on, the
value it should be set to, and a list of parameters which are required
if the required parameter is set to the required value.
Adds new settings for managing retry files:
* retry_files_enabled, defaults to True
* retry_files_save_path, defaults to ~/.ansible-retry
This change was adapted from PR #5515.
The message for when an async task has finished has the hostname in it. This adds it to the polling message as well:
```
<job 390794962174.18311> finished on 107.6.24.140
<job 390794962174.31779> finished on 69.90.50.171
<job 390794962174.12328> polling on 69.90.50.172, 6840s remaining
```
The two detection methods currently implemented do not cover all cases.
For example qemu guests invoked like this:
qemu -machine pc-i440fx-1.4,accel=kvm -cpu SandyBridge
return this information:
product_name: Standard PC (i440FX + PIIX, 1996)
cpuinfo: model name : Intel Xeon E312xx (Sandy Bridge)
Fixes a case where the variable 'foo' may exist, but the with_items loop
was used on something like 'foo.results', where 'results' was not a valid
attribute of 'foo'. Prior to this patch, conditionals were not evaluated
until later, meaning there was no opportunity to allow a test to skip the
task or item based on it being undefined.
This fixes the case in which the delegated to host may not be in the
specified hosts list, in which cases facts/vars for the host were
not available in the injected hostvars.
This also fixes the inventory variable fetching function, so that an
unknown host raises a proper error as opposed to a NoneType exception.
Fixes#8224
