ENH: add git information to the template tool, if available

[klauer]

Partially addresses #251

[klauer]

This is a bit sloppy, but it's working to generate this page currently: https://pcdshub.github.io/plc-summary/index.html

[ZLLentz]

Wow, look at all those no-tag plcs!

[klauer]

Yeah, that was a bit of a surprise... :(

[ZLLentz]

Some of these seem weird, like the lcls-plc-kfe-motion one:
v1.3.1-28-gd86661a
Which is 28 tags after v1.3.1, but that commit is tagged at v1.3.4

[ZLLentz]

Ahh, it's because the tc_release tags are not on master branch!

[klauer]

Yep - that confused me for way longer than I'd like to admit:

lcls-plc-kfe-motion klauer$ git tag
v1.0.0
v1.1.0
v1.2.0
v1.3.0
v1.3.1
v1.3.2
v1.3.3
v1.3.4
lcls-plc-kfe-motion klauer$ git describe --tags
v1.3.1-28-gd86661a

And as you noted, the tags are on a separate branch... Not sure if any git-fu can help us out here in an easy/repeatable way.

[ZLLentz]

This is all I've got after some googling/experimenting:

zlentz@psbuild-rhel7-01$ git describe --contains `git rev-parse HEAD`
v1.3.4~1
zlentz@psbuild-rhel7-01$ vim some_file.txt
zlentz@psbuild-rhel7-01$ git add some_file.txt
zlentz@psbuild-rhel7-01$ git commit -m "test"
[master 6780612] test
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 some_file.txt
zlentz@psbuild-rhel7-01$ git describe --contains `git rev-parse HEAD`
fatal: cannot describe '6780612d1b19edc8ba83c2c40700cd88d4a54143'
zlentz@psbuild-rhel7-01$ git describe --tags
v1.3.1-29-g6780612

[klauer]

Hmm, will give that a try and see how it looks - one sec.

Better, probably:
