config/cmdline/cmdline.go unconditionally splits /proc/cmdline on spaces.

However, kernel documentation explicitly states that parameters can contain spaces if they're surrounded by double quotes.

Implementing a proper parsing would allow to pass more complex parameters to an initial cloud-config using the cc. key prefix.

For example, one could boot RancherOS with a kernel command line like

cc.ssh_authorized_keys="[ssh-rsa AAA....]"

to get a public key in place if needed, being way more secure than the rancher.password parameter.

Support More Complex Cmdline Configuration
ce6253c 
Fixes rancher#2755. Allows for quoted arguments with spaces in the kernel cmdline to be parsed properly.

Example: https://play.golang.org/p/GZAUM5cWKJJ

An example command line:

```
$ cat /proc/cmdline
earlyprintk=serial console=ttyS0 rancher.autologin=ttyS0 rancher.defaults.hostname=ros-vm1 rancher.defaults.network.dns.nameservers=[192.168.64.1] rancher.network.interfaces.eth0.dhcp=true rancher.network.interfaces.eth1.dhcp=false rancher.network.interfaces.eth1.address=192.168.99.11/24 rancher.state.dev=LABEL=RANCHER_STATE rancher.state.autoformat=[/dev/vda] rancher.state.formatzero cc.ssh_authorized_keys=['ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBOz8mD0tRrNsHBLHD5jVgmXO26JA7eKFZrj4Ic9KR2y3qXlxU9JCYYn/qDyTCmExt8Rw6SaU/BvgU7WT3Bjsi6c=','ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJj5mkpBHBBAW5XClcB5aFTWph+VCL7I0W8gm93AT5w4','ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDKfb0O2qXgIgrtD5Mj7fBYdg4jMrT7wetBbkG2e4maDsRR3AtSYjEB3NeEifM8gdvIf0gYs1BNB/Ar76agaQGeqW+Ewb2LWdypr4Ipw09yWCrC9ttVbCnHuzVLYjML0CNgpjIRC+FC5r1X1gm2LufRN4orZ1NQvNhRRWJVT37vRtHo79TecK0DKQmy87Zpj3cNiI/5iObnTk56pZWpIAEiC5hEVkcVxmdkLJs3YonWVZzmK/Y8uvFtF+GhA6Jcpc38zDQHKsOjFWvj3qbWtVEQteNDxsM2pNeXY5wdrhRn4YSdKme9Cm7CdAogIdAdPtqPIfq/jY0QczS12qFZH7zt']

```

This is still a bit fragile. For example there can be no space after the commas in the ssh_authorized_keys list. The quoting used above is the only combo I found that works. Also EXTRA_CMDLINE still has part of the last pub key in it.

Support More Complex Cmdline Configuration
bfa2592 
Fixes #2755. Allows for quoted arguments with spaces in the kernel cmdline to be parsed properly.

An example command line:

```
$ cat /proc/cmdline
earlyprintk=serial console=ttyS0 rancher.autologin=ttyS0 rancher.defaults.hostname=ros-vm1 rancher.defaults.network.dns.nameservers=[192.168.64.1] rancher.network.interfaces.eth0.dhcp=true rancher.network.interfaces.eth1.dhcp=false rancher.network.interfaces.eth1.address=192.168.99.11/24 rancher.state.dev=LABEL=RANCHER_STATE rancher.state.autoformat=[/dev/vda] rancher.state.formatzero cc.ssh_authorized_keys=['ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBOz8mD0tRrNsHBLHD5jVgmXO26JA7eKFZrj4Ic9KR2y3qXlxU9JCYYn/qDyTCmExt8Rw6SaU/BvgU7WT3Bjsi6c=','ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJj5mkpBHBBAW5XClcB5aFTWph+VCL7I0W8gm93AT5w4','ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDKfb0O2qXgIgrtD5Mj7fBYdg4jMrT7wetBbkG2e4maDsRR3AtSYjEB3NeEifM8gdvIf0gYs1BNB/Ar76agaQGeqW+Ewb2LWdypr4Ipw09yWCrC9ttVbCnHuzVLYjML0CNgpjIRC+FC5r1X1gm2LufRN4orZ1NQvNhRRWJVT37vRtHo79TecK0DKQmy87Zpj3cNiI/5iObnTk56pZWpIAEiC5hEVkcVxmdkLJs3YonWVZzmK/Y8uvFtF+GhA6Jcpc38zDQHKsOjFWvj3qbWtVEQteNDxsM2pNeXY5wdrhRn4YSdKme9Cm7CdAogIdAdPtqPIfq/jY0QczS12qFZH7zt']
```

Results in:

```
