run-container: uncomment baseurl in yum.repos.d/*.repo when using a proxy
When using a proxy it is often useful to know in advance which mirrors
are to be contacted, so a whitelist can be set up. This is not easy when
using the yum.conf(5) mirrorlist option, as the retrieved list of mirrors
may change. The repository definition may also specify a canonical mirror
with the 'baseurl' option; this option is often commented out by default
to favor the usage of worldwide mirrors. This patch uncomments 'baseurl'
when an http_proxy is being used, so the canonical mirror is used *in
addition to* the mirrors retrieved from the mirrorlist.
lxd: install zfs-linux instead of zfs meta package
When using the LXD module cloud-init will attempt
to install ZFS if it does not exist on the target
system. However instead of installing the `zfsutils-linux`
package it attempts to install `zfs` resulting in an error.
Ubuntu Xenial (16.04) has zfs meta package, but Bionic (18.04)
does not. Use the specific base package instead of zfs meta.

net: Make sysconfig renderer compatible with Network Manager.
The 'sysconfig' renderer is activated if, and only if, there's ifup and
ifdown commands present in its search dictonary or the network-scripts
configuration files are found. This patch adds a check for Network-
Manager configuration file as well.
This solution is based on the use of the plugin 'ifcfg-rh' present in
Network-Manager and is designed to support Fedora 29 or other
distributions that also replaced network-scripts by Network-Manager.

net: Wait for dhclient to daemonize before reading lease file
cloud-init uses dhclient to fetch the DHCP lease so it can extract
DHCP options. dhclient creates the leasefile, then writes to it;
simply waiting for the leasefile to appear creates a race between
dhclient and cloud-init. Instead, wait for dhclient to be parented by
init. At that point, we know it has written to the leasefile, so it's
safe to copy the file and kill the process.
cloud-init creates a temporary directory in which to execute dhclient,
and deletes that directory after it has killed the process. If
cloud-init abandons waiting for dhclient to daemonize, it will still
attempt to delete the temporary directory, but will not report an
exception should that attempt fail.
[Azure] Increase retries when talking to Wireserver during metadata walk
Testing startup of large numbers of VMs (of varying distros) in Azure
shows that 3 retries results in a small percentage of failed VMs.
Increasing that by a few dramatically decreases the occurrence of
provisioning timeout errors. The initial choice of "3 retries" was
uninformed by heavy testing. Also, the alternate provisioning
mechanism for Azure (waagent) retries the Wireserver crawl without
limit. 10 retries seems a more reasonable choice.
