K8s 1.15

* bump traefik version

Changed SELinux/semanage error to fatal

If the install errors out on semanage not found, a file not found is
thrown as a 'file not found' for error. Updating to 'fatal' resolves
this as the script then exits as intended and throws an 'error'.

install.sh: Use -eq instead of = for integer comparison

Check for semanage command availability

install.sh: Use contemporary command substitution syntax

Integrate Kine

For integer comparison, it is recommended to use '-eq' instead of the
broader comparison '='. From the manual:

n1 -eq n2  True if the integers n1 and n2 are algebraically equal.
s1 = s2    True if the strings s1 and s2 are identical.

The install.sh script currently uses a mix of the legacy backquote
syntax and the recommended contemporary $() syntax. This patch brings
consistency by replacing the occurrences of the legacy backquote ones
with the $() syntax.
