[completion] Filter out non-hostnames in SSH config file (#1329)

Browse Source 
* Correctly exclude SSH config options with Host

SSH config files have 14 options containing 'Host'.
Previously The zsh and bash completion scripts would include lines
containing these options when doing command-line completion of SSH hosts
with `ssh **`.

This commit fixes that problem by only including lines with 'host '.

* Don't autocomplete SSH hostnames using ?

SSH config files support ? as well as * for wildcards in Host lines.
This commit excludes lines containing ? for zsh/bash command line
completeion using `ssh **`
