Open5GS documentation instructs to install into open5gs.git/install/
during build [1]:
"""
$ cd open5gs
$ meson build --prefix=`pwd`/install
$ ninja -C build
"""
As a result, this directory appears all the time when using git, since
it's not in the .gitignore file. Add it.

* Initial metrics support based on Prometheus
This commit introduces initial support for metrics in open5gs.
The metrics code is added as libogsmetrics (lib/metrics/), with a well
defined opaque API to manage different types of metrics, allowing for
different implementations for different technologies to scrap the
metrics (placed as lib/metrics/<impl>/. The implementation is right now
selected at build time, in order to be able to opt-out the related dependencies
for users not interested in the features. 2 implementations are already
provided in this commit to start with:
* void: Default implementation. Empty stubs, acts as a NOOP.
* prometheus: open5gs processes become Prometheus servers, offering
states through an http server to the Prometheus scrappers. Relies on
libprom (prometheus-client-ci [1] project) to track the metrics and format
them during export, and libmicrohttpd to make the export possible through
HTTP.

The prometheus-client-c is not well maintained nowadays in upstream, and
furthermore it uses a quite peculiar mixture of build systems (autolib
on the main dir, cmake for libprom in a subdir). This makes it difficult
to have it widely available in distros, and difficult to find it if it
is installed in the system. Hence, the best is to include it as a
meson subproject like we already do for freeDiameter. An open5gs fork is
requried in order to have an extra patch adding a top-level
CMakeList.txt in order to be able to includ eit from open5gs's meson
build. Furthermore, this allows adding bugfixes to the subproject if any
are found in the future.
* [SMF] Initial metrics support
* [SMF] Add metrics at gtp_node level
* docs: Add tutorial documenting metrics with Prometheus
* [SMF] Fix potential null pointer dereference
Pointer "sess" was first dereferenced and later on checked for nullness.
This is clearly wrong. Rearrange the code path to make sure the check is
done first, then dereferenced.
* gitignore: Add subprojects/libtins
* cosmetic: Fix whitespace
* protects db endpoints with auth data, but will require ui updates to function properly
* adds an Authorization header with bearer token to all api/db/* request endpoints
* force login if token doesn't exist
* remove debug code
Adding this 'debian' subdirectory will allow users to build
binary packages using 'dpkg-buildpackage' and related tools.
Tested so far on Debian unstable and 9 as well as Ubuntu 17.04
and 17.10 on OpenSuSE Build Service.
'mmed' and the like all are a bit of a generic name. Let's prefix the
project name to ensure there will be no clashes with other programs that
also implement a 'MME daemon' or the like.
