add support for podman-remote image scp as well as direct access via the API. This entailed
a full rework of the layering of image scp functions as well as the usual API plugging and type creation
also, implemented podman image scp tagging. which makes the syntax much more readable and allows users t tag the new image
they are loading to the local/remote machine:
allow users to pass a "new name" for the image they are transferring
`podman tag` as implemented creates a new image im `image list` when tagging, so this does the same
meaning that when transferring images with tags, podman on the remote machine/user will load two images
ex: `podman image scp computer1::alpine computer2::foobar` creates alpine:latest and localhost/foobar on the remote host
implementing tags means removal of the flexible syntax. In the currently released podman image scp, the user can either specify
`podman image scp source::img dest::` or `podman image scp dest:: source::img`. However, with tags this task becomes really hard to check
which is the image (src) and which is the new tag (dst). Removal of that streamlines the arg parsing process

Firstly, reset is now managed by the runtime itself as a part of
initialization. This ensures that it can be used even with
runtimes that would otherwise fail to be created - most notably,
when the user has changed a core path
(runroot/root/tmpdir/staticdir).
Secondly, we now attempt a best-effort removal even if the store
completely fails to be configured.
Third, we now hold the alive lock for the entire reset operation.
This ensures that no other Podman process can start while we are
running a system reset, and removes any possibility of a race
where a user tries to create containers or pull images while we
are trying to perform a reset.
[NO NEW TESTS NEEDED] we do not test reset last I checked.

For the AutocompleteFormat function we expect the correct template
struct which is used in the golang template. The function can handle
both struct and pointer to a struct. Using the reference is more
efficient since it doe snot have to copy the whole struct.
Also change some structs to use he actual type from the template instead
of some nested one to make sure it has to correct fields.
Signed-off-by: Paul Holzinger <pholzing@redhat.com>
AutocompleteFormat() takes the format struct as argument. Often the structs
are deeply nested and contain other structs. Up until now if there was a
pointer to a struct the logic was not able to get the field names from
that, simply because the pointer was nil. However it is possible to
create a new initialized type with reflect.New(). This allows us to
complete all struct fields/functions even when there nil pointers.
Therefore we can drop the extra initialization which was done by some
callers.

The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

When podman gets an error it prints out "Error: " before
printing the error string. If the error message starts with
error, we end up with
Error: error ...

logrus.Error() also prints out that this is an error, so no need for the
error stutter.

The calculate the percentage we need floating point numbers. The current
code however casted the result of reclaimable/size to an int first.
Casting to an int in go will just discard the decimal points, thus the
result was either 0 or 1 so if multiplied by 100 it would show up as 0%
or 100%.
To fix this we have to multiply by 100 first before casting the result
to an int. Also add a check for div by zero which results in NaN and use
math.Round() to correctly round a number.

podman system prune should also remove all networks. When we want to
users to migrate to the new network stack we recommend to run podman
system reset. However this did not remove networks and if there were
still networks around we would continue to use cni since this was
considered an old system.
There is one exception for the default network. It should not be removed
since this could cause other issues when it no longer exists. The
network backend detection logic ignores the default network so this is
fine.
