debianize influxdb-python

so that we can generate a debian package with command:
dpkg-buildpackage -us -uc
update .gitignore
update deb packaging for requirement requests>=1.0.3

this is required because influxdb-python uses response.json() api
(json was not callable before requests version < 1.0.3)
Merge branch 'debian-packaging' into helioslite
update debian/changelog to version 0.1.4-2+hl~1

(to match helioslite versioning scheme)
update debian/changelog to version 0.1.4-2+hl~2
update debian/changelog to version 0.1.4-2+hl~3
