[oe] mongodb and itstool depend on meta-python

[Yi Zhao]

Hi,

Ideally, the meta-oe should not depend on other layers except oe-core 
layer. But I found there are 2 recipes mongodb and itstool in this layer 
depend on some python packages in meta-python layer:

ERROR: Nothing PROVIDES 'python-pyyaml-native' (but 
/buildarea/openembedded-core/meta-openembedded/meta-oe/recipes-dbs/mongodb/mongodb_git.bb 
DEPENDS on or otherwise requires it).
ERROR: Nothing PROVIDES 'python-cheetah-native' (but 
/buildarea/openembedded-core/meta-openembedded/meta-oe/recipes-dbs/mongodb/mongodb_git.bb 
DEPENDS on or otherwise requires it).
ERROR: Nothing PROVIDES 'python-typing-native' (but 
/buildarea/openembedded-core/meta-openembedded/meta-oe/recipes-dbs/mongodb/mongodb_git.bb 
DEPENDS on or otherwise requires it).
ERROR: Nothing PROVIDES 'python3-lxml-native' (but 
/buildarea/openembedded-core/meta-openembedded/meta-oe/recipes-support/itstool/itstool_2.0.5.bb 
DEPENDS on or otherwise requires it).

Should we move these python recipes from meta-python to meta-oe?
