Add force_rebuild option in kdump.conf
Some user need always force rebuild the dumprd, add an kdump.conf
option force_rebuild here. If force_rebuild is set to 1
kdump initrd will be rebuilt every time then the service starts.
Testing:
Tested below cases:
force_rebuild
force_rebuild 0
force_rebuild 1
force_rebuild 2

Currently net options means either nfs or ssh dump.
Better to split these two into standalone options. That's more clear to user.
after the split, ssh dump need user specify "ssh user@host"
nfs dump need user specify "nfs host:nfsshare"

we now switched to systemd, 'service kdump propagate' does not work anymore.
update the alert message to use 'kdumpctl propagate'
vivek: update kexec-kdump-howto.txt as well.

Original patch is from Amerigo, but it has changed a lot:
remove multi dump
refreshed with latest git for the dump instruction function restructure
fixed the behavior of do_kdump_pre, if kdump_pre fails it will reboot
update the docs
check the existance and executable of kdump_pre/post files,
also check the timestamp of them for rebuilding.
refresh patch,
Address comments from vivek:
s/hush/bash in docs
fix the copy-paste error in kdump post error message
s/reboot\/halt/reboot in kexec-kdump-howto.txt

Resolves: bz805778
Simply the logic and optimize the code
Move check_exist, check_executable, rebuild_initrd to functions
remove BOOTDIR which is not used
Note: There might be modules which are newer than last built initramfs,
we always rebuild the initramfs when extra_moduels= is specified.

kdumpctl: save_raw if found vmcore
mkdumprd: checking available size of raw disk
dracut module: do the dumping
Note, add a dir /kdumpscripts for monitor_dd_progress and future
kdump scripts
[v1->v2]: monitor_dd_process become a script instead of a function
add missed utils
use pipe with dc
[v2->v3]: Don: fix dd_progress_file typo
Vivek: move [ -f $conf_file ] earlier
don't split keyfile= and [ -f keyfile ]
move default core_collector earlier
move non-makedumpfile warnings to mkdumprd
make check available size a common function
Amerigo: use less pipe for grep then awk print
use shell (( )) instead of dc
use cut instead of awk
no need install dc and awk
make DD_BLKSIZE a variable
don't add 0755 file in git, chmod in module-setup.sh
[v3->v4]: vivek: kdumpctl multi raw target handling
monitor_dd_progress- fix wrong size calculation:
the tail -1 of dd pregress file is in bytes instead of blocks
only print the whole dd src file size for non-filtered case
check [ -b raw target device ] before dump
[v4->v5]: vivek: move check [ -b $1 ] before monitor_dd_progress
remove multi target function
[v5->v6]: vivek: only warning for raw dump of non-makedumpfile core_collector
[v6->v7]: kdumpctl should return 0 when there's no raw target

remove multi dump
Resolves: bz816859
multi dump was not written as a failsafe dump. Also it was not really tested.
It introduced more complexity in the early phase of porting plenty of rhel6
functions, so we'd remove it and concentrate on the base functionalities.
[v1->v2]: vivek: better error message

Resolve: bug 807521
The fix is easy.
Command sed should be called with option -n to remain slience when DUMP_TARGET
is a nfs server like 'nfs.server:/mnt/testarea/nfs'.
Then nfs function check_ssh_config will return 1 to not to config nfs like a
ssh dump

Add ssh dump support
changes including below items:
1. sshkey option
2. sshkey propagate
3. fix a bug of _server ip calculation for dump target string
4. change the prefix of kdump hook from 93 to 01 to avoid dhclient and
other cleanups happening before us
5. enable network with dracut cmdline rd.neednet=1 when there's network
target config
[v1 - v2]:
Only check_ssh_target when there's ssh dump target in kdump config file
[v2 -> v3]
style fixes: trailing spaces and space before tab indent
remove set -x
simply check_ssh_target
use awk to get sshkey option value
change pivot hook order to 0000
