xmlsec1 binary should not be configured with entity

[rhoerbe]

It is a different topic than entity configuration, is not a concern of the calling program and causes redundancy in an application with many configurations.

Proposed resolution:

• pysaml2 shall handle it internally:
• first it should look for an ENV variable
• second it should look for a separate pysaml config file
• third it should use the configuration passed in the API (for backwards compatibility)
• fourth it should look at the canonical locations for various OS, such as /usr/bin, opt/local/bin and /usr/local/bin.

Where are we with this? I just ran into this issue and i have to modify the source to get it to work. Im on osx10.12 and now /usr/bin is completely off limits without doing some nasty little hacks and rebooting.. can we get some traction on this?
