Change normed to density in numpy and matplotlib histograms within LALInference
Description
The use of the argument normed=True in histograms from matplotlib and numpy is deprecated since a few versions ago in either package. This leads to warnings like
/home/soichiro.morisaki/local/gwcelery_envs/gwcelery_lalsuite659/lib/python3.6/site-packages/lalinference/bayespputils.py:3987: MatplotlibDeprecationWarning:
The 'normed' kwarg was deprecated in Matplotlib 2.1 and will be removed in 3.1. Use ‘density’ instead.
(n, bins, patches)=plt.hist(pos_samps,histbins,normed='true',facecolor=‘grey’)
Generating 1D plot for a1z.but it's easily fixed by switching to density=True for all these instances.

It technically breaks backwards compatibility with numpy versions from 1.5 and backwards (Numpy 1.5 was released in 2010). It also breaks compatibility with matplotlib 2.0 (released in 2017).
