The recent PR #883 replaced the standard overlay naming convention with
static names for each of the runtime and wwinit/system contexts; but the
method by which it left the "legacy" naming convention in place led to a
bug where warewulfd was still attempting to serve overlays with the
previous naming convention, though this name wasn't being built.
This PR refactors contextual overlay image naming to be, I think, a more
typical golang pattern, and updates affected code to match.
This PR also included tests for all functions modified by this change.
Fixes#896

I noticed that some wwlog calls included a trailing newline, but others
did not. I tested both in isolation and discovered that the behavior was
consistent regardless of whether a trailing newline was included. I
further confirmed in code that wwlog appends a trailing newline
automatically if it is not present; so a trailing newline is unnecessary
in individual calls.
This commit removes trailing newlines from all calls to make them
consistent. It also replaces two calls to wwlog.Printf. (see #534)

wwlog provides named loggers for each level, which requires
less code and is clearer than wwlog.Printf. The code has
included a mix of both, but this commit consolidates existing
code on the per-level functions.

The `wwctl overlay parse -n NODE FILE` will interpret the given overlay file and print it stdout, via wwlog.PRINTF.
The overlay code had to be refactored for this, but hopefully this makes the code a bit more readable. Also the tstruct has not its own initilization code.
* Combine provision response handling, add hwaddr and interface to dhcp
* Simplify stage cases, add backward compatible uri parse
* Move control of image compression to client
* Fix kernel search path for ubuntu, buffer template generation
* Implement cpio and gz as functions, add log named functions
* Generalize fs image creation routine
* Combine daemonLogf to generalized wwlog
* Fix template newline insertion, update dhcp and hosts tmpl
* Update IPXE template to handle non-compressed files
* Update DHCP template to set network interfaces and server IP assignment
* Update DHCP/hosts templates to choose a host-name self-consistently
If there is a user writeable file in the host overlay, a user can
create arbitrary files on the host root file system. Although these
files will belong to this user, this might allow users to modify
any files.
So this patch restricts the access to the host overlay to root and
produces a warning if this was changed.
Every network in the profile and for the nodes can have induvidual keys values
pairs, called Tags, which are propergated to the templates. So they can be used
for things like MTU size like
`wwct node set node01 --nettag mtu=9000`
and in in ifcfg.xml.ww
```
{{ if $netdev.Tags.mtu -}}
<mtu> {{ $netdev.Tags.mtu }} </mtu>
{{ end -}}
```
