Merged #61, #72, #73

• Replaced glide with go modes
• aws-sdk-go updated to v1.30.4
• Replaced uuid generator with lightweight Mongo BSON ObjectID
• Implemented HTTP Basic Auth
• Implemented HTTP timeout
• Fixed Kibana redirection issues
• Removed all annoying 'log.Fatalln' lines.
• Removed restrictions on endpoints. Any Elasticsearch endpoint can be used with the proxy, not only Amazon Elasticsearch.

Clean the requested path before signing the request. Fixes #38

Small fix to meet satori's uuid change.

• Content-Type is now mandatory for ES 6+. More information here: https://www.elastic.co/blog/strict-content-type-checking-for-elasticsearch-rest-requests

• This release is enforcing on user's entered value for Content-Type. This seems to be required for Kibana too.

Release Notes

This version comes with major changes.

• Most of the code was rewritten.
• Added ability to disable signing the requests. This should make aws-es-proxy work with any ElasticSearch installation.
• Added functionality to log client requests and server responses to log files for debug.

Notes:

At the moment, the log files are not being automatically rotated, so keep an eye on the file size.
If you are going to use Kibana most of the time, we recommend you to not enable file logging option as this will generate huge amount of unreadable data (Kibana webapp will be entirely written to the log file).

Release Notes:

• Add header 'Content-Type: application/json' if specified in the calling client (e.g. curl). This is required for Amazon ElasticSearch 6.0

• Auto refresh AWS Credentials (thanks to diranged@ for the patch)

• Added DockerFile (thanks to em0ney@ for the patch)

WARNING: This new version is still under test. If you face issues, please open an issue ticket.

What is new?

• Verbose mode shows the body request now.

• This feature intends to help developers identifying slow queries with minimum efforts.

• Added a '-pretty' mode (works with -verbose) which will prettify the verbose output and re-format the body json output.

• Special thanks to zqben402 for writing the body dump patch.

• Thanks to dlackty for reformatting readme document.

Made it work with Amazon ElasticSearch 5.1 and Kibana 5.1.1

Small improvements.

Initial release. Use with caution!
