Public bug reported:

This might be a subtle error which is neither a direct package
dependency nor explicitedly an error in the cloud-init software, but
this in fact leads to problems. Also, it does not seem to be a distro-
specific problem.

Scenario:

1. User of cloud-init is not aware it will use wget to download meta-data
2. There is no direct dependency in the cloud-init package to wget (checked for Ubuntu and SLES 15)
3. Cloud-init will not work properly as wget is missing

Error output from /etc/cloud-init.log (observed with lastest patch level
for version 19.4 on SLES 15)

2020-10-22 14:08:05,095 - util.py[DEBUG]: Running command ['wget', '--quiet', '--tries', '3', '--timeout', '20', '--output-document', '-', '--header', 'DomU_Request: send_my_password', '192.168.1.1:8080'] with allowed return codes [0] (shell=False, capture=True)
FileNotFoundError: [Errno 2] No such file or directory: b'wget': b'wget'
Command: ['wget', '--quiet', '--tries', '3', '--timeout', '20', '--output-document', '-', '--header', 'DomU_Request: send_my_password', '192.168.1.1:8080']
Reason: [Errno 2] No such file or directory: b'wget': b'wget'

Suggestion: possibly, cloud-init should exit immediately if wget not
detected in the system, and/or have it as a dependency in distro
packages?
