Since da03653908aea9a62f805faf0328f7b2f046abaa slapos.core's slapproxy transmit
more parameters, so adapt tests to account for it.

nis module is linking against system libraries

This is almost the smae as for python3 (see e1cee1fc)

- rubygemsrecipe deployment mode now depends on `allow-picked-versions` by default

sotware/caddy-frontend: Use instance-caddy-replicate.cfg to replace buildout-switch-softwaretype.cfg

Because when using the switch-software, the
buildout-switch-sofwtwaretype.cfg will not be generated, see
https://lab.nexedi.com/nexedi/slapos/blob/master/slapos/recipe/softwaretype.py#L264-267
So use instance-caddy-replicate.cfg instead, which has same effect.

Changes explanation:
slave_reference.lower(): The configparser which the current buildout
using is case sensitive, which cause some options cannot be found.
slap_software_type: The recipe softwaretype need this option, but
switch-softwaretype doesn't.
caddyprofiledeps: It provides the deps of caddy. Switch to
switch-softwaretype leads to the error like "ImportError: No module
named furl". Force caddyprofiledeps installed first can solve this
issue.

See theia's [changelog](https://github.com/eclipse-theia/theia/blob/v1.16.0/CHANGELOG.md#v1160---7292021), we update from 1.13.0 to 1.16.0.

Changes specific to slapos port:
 * We set `warnOnPotentiallyInsecureHostPattern` because the new warning is very intrusive ... but it might actually be very insecure. For now we don't have solution. We are tracking this in https://erp5js.nexedi.net/#/bug_module/20210819-20614EE
 * New libsecret component that is now required by theia
 * Switch to using vscode git instead of theia git, to use timeline ( see https://github.com/eclipse-theia/theia/pull/7997 )
 * globally version up slapos.core to https://pypi.org/project/slapos.core/1.6.18/

See merge request nexedi/slapos!1039

To have the timeline view

This is basically the same problem as in 1b291415
(component/ghostscript: Workaround for slaprunner paths with double
slashs, 2021-06-02)

The issue is now fixed in 1.16.0

Eventhough our current pattern is not the most secure, we have no other
choice for now that to use such insecure patterns.

In https://erp5js.nexedi.net/#/bug_module/20210819-20614EE we track possible
improvements to this situation.
