* New config option `CLICON_USER` with default value `clicon`

# RFC 6241:
# 7.3 - Even if it advertises the :writable-running capability, a device
# MAY choose not to support the <running/> configuration datastore
# as the <target> parameter of a <copy-config> operation.
# - If the <source> and <target> parameters identify the same URL or
# configuration datastore, an error MUST be returned with an error-
# tag containing "invalid-value".
# 8.3.5.1 The candidate configuration can be used as a source or target
# 8.4.1 If :startup capability is advertized, <copy-config> from running to
# startup is also necessary
# 8.8.5.2 :url capability <copy-config> accepts <url> element as value of
# the <source> and the <target> parameters.
#
# The test checks that these are allowed:
# running->startup
# running->candidate
# candidate->startup
# startup->candidate
# And checks that copying to running is not allowed
# Magic line must be first in script (see README.md)
