remotenames: introduce a class to lazily resolve remotnames
remotenames may take time to load and in next patch we are going to introduce
namespaces related to them. So let's introduce a class making them load lazily.
This is a part of moving hgremotenames extension to core.

Clear rules when there are includes
$ hg debugsparse --include *.py
$ ls
data.py
$ hg debugsparse --clear-rules
$ ls
base.sparse
data.py
index.html
readme.txt
webpage.sparse
Clear rules when there are excludes
$ hg debugsparse --exclude *.sparse
$ ls
data.py
index.html
readme.txt
$ hg debugsparse --clear-rules
$ ls
base.sparse
data.py
index.html
readme.txt
webpage.sparse
Clearing rules should not alter profiles
$ hg debugsparse --enable-profile webpage.sparse
$ ls
base.sparse
index.html
webpage.sparse
$ hg debugsparse --include *.py
$ ls
base.sparse
data.py
