Potential maintenance and migration away from paste

[fmigneault]

Issue

Considering pasteorg/paste#91 discussing cease of development of paste, following definitions might need to be adjusted.

Magpie/config/magpie.ini

Lines 106 to 108 in 9bb053a

	[app:api_app]
	use = egg:Paste#static
	document_root = %(here)s/ui/swagger

Magpie/config/magpie.ini

Lines 110 to 113 in 9bb053a

	[filter:urlprefix]
	use = egg:PasteDeploy#prefix
	# prefix must be adjusted according to 'MAGPIE_URL' / 'magpie.url'
	prefix = /magpie

Magpie/config/magpie.ini

Lines 6 to 10 in 9bb053a

	[composite:main]
	use = egg:Paste#urlmap
	/ = magpie_app
	#/api = api_app
	#/magpie/api = api_app

Potential Solutions

For urlmap, this is supposed to be a drop-in replacement https://rutter.readthedocs.io/en/latest/#declarative-configuration-using-paste-deploy-ini-files (reference pasteorg/paste#91 (reply in thread)).

The PasteDeploy is supposed to be unaffected (pasteorg/paste#91 (reply in thread)).

For static, tests must be done to validate if there is an impact or not.
