Add redirections for upper/mixed case checksum

• Add docstring

rebase with master

• Add uppercase redirections for APIs and tests

@anlambert I have locally made changes for other endpoints also and added tests for the same. Should I create a new Diff?

rebase to master

squashed commits

• add SearchDelay to admin DataTables

@anlambert Oh the admin ones. Will update.
Anyways, how do I test as admin when I run it locally?

@anlambert history.immutable is already set to true.

or, actually, we can just also add a fulltext index to URLs and be done with it https://www.postgresql.org/docs/11/textsearch-intro.html#TEXTSEARCH-MATCHING

As just pointed out by @olasd on IRC, this is in fact D561. Fancy taking that up, @kalpitk ?

• add case for bigger array lengths

My laptop crashed when I entered a big query on /browse/search/ , because it filled my whole RAM.
Array size of 10 filled my 4 GBs of RAM when heapsPermute was called

Add support for uppercase sha1 in url arguments

Created new diff by mistake.

• fix failing tests

• remove lower calls from endpoints

• fix uppercase sha1 and tests

@kalpitk, I am ok with your tests plan but there is still some work to do here:

• remove the calls to the lower method inside endpoint implementations (as I said, this is not needed)
• there is numerous other endpoints that need to be processed (simply search for [0-9a-f] inside the swh-web codebase to identify them)
• tests implementation must be factorized as test_* and test_*_with_uppercase_sha1 are basically the same thing

Continued in D1290

• improve readability

@anlambert Oh i didn't read your comment. Anyways, I just wrote some tests.

• fix uppercase SHA1 for api
• add tests for uppercase sha1

@anlambert I'll update for api endpoints also.

• fix failing tests

• fix upper case SHA1 in multiple files

I pushed changes through arc : D1290
Probably the problem was line 34, which had more than 79 characters. This was preventing me to stage changes.

@ardumont Changed the title.
