4799d21e01 pkg/osutil: fix IsExist 
Currently it returns true for "/some/existing/file/foo"
because that returns ENOTDIR.

e130d95518 vm/gce: accept un-tar-ed image 
vm/gce differs from other VM types in that it accepts image
in a weird, GCE-specific format (namely, image named disk.raw
is put into .tar.gz file). This makes it impossible to write
generic code that creates images for any VM types.

Make vm/gce accept just image like e.g. vm/qemu
and handle own specifics internally.

97b58e7eae syz-manager/mgrconfig: move sshkey from vm config to manager config 
Sshkey is a property of image, which is in manager config.
Move sshkey to the same location as image.

The motivation for the move is as follows.
Continuous build produces an image and the key,
both need to be passed manager instance.
Continuous build system should not distinguish
different VM types and mess with their configs.

NOTE FOR USERS: this breaks manager configs again.
Hopefully the last time for now. Docs are updated.

260cdaa2b2 syz-manager/mgrconfig: remove output param 
It was useful only for vm/local which was removed.
The param wasn't documented and if one tries to change it,
it will break manager in obscure way (i.e. spurious
"test machine is not executing programs" crashes).

d5406e5fba delete .clang-format.email 
The format is present in pkg/csource and we generally use that.
.clang-format.email is unused as far as i know, delete it.

a853b91c58 syz-manager/mgrconfig: allow loading from memory 
Allow loading manager config from memory.

75c73461d8 syz-manager/config: rename to syz-manager/mgrconfig 
We have 2 packages with the same name: pkg/config and syz-manager/config.
This leads to constant clashes. We either rename one to pkgconfig or
another to mgrconfig. This is not good and will become worse when/if
we have another program-specific config in a separate package.

Rename manager config to mgrconfig.
Other program-specific configs can use the same convention
in future -- fooconfig.

2200ced89b syz-manager: improve vm management during repro 
1. Don't start reproducing crashes until we triage
   all inputs from corpus and hub. This minimizes
   chances of losing inputs from hub. Also allows
   to faster get idea of total coverage.
2. Fix bug when vmCount%instacesPerRepro != 0.
   Currently we stop the remainder of instances
   and it stays idle.
