8a41cd03a5 journal: fix reading omaps from objects with large key counts
The implementation of getOMapValues assumed that the number of key-value
pairs assigned to the object would be close to the number of keys
being requested. When the number of keys on the object exceeded the
"listExcess" value the function would fail to read additional keys
even if they existed in the omap.
This change sets a large fixed "chunk size" value and keeps reading
key-value pairs as long as the callback gets called and increments
the numKeys counter.

8393fbe40b util: simplify error handling
The sentinel error code had additional fields in the errors, that are
used nowhere.  This leads to unneccesarily complicated code.  This
change replaces the sentinel errors in utils with standard errors
created with errors.New() and adds a simple JoinErrors() function to
be able to combine sentinel errors from different code tiers.

de74c36d8c cleanup: address err113 warnings about direct error comparisons
Several places in the code compared errors directly with the go-ceph
sentinel errors.  This change uses the errors.Is() function of go
1.13 instead.  The err113 linter reported this issue as:

err113: do not compare errors directly, use errors.Is() instead

09e1c856d0 journal: do not return errors from remove omap func if omap missing
The previous function used to remove omap keys apparently did not
return errors when removing omap keys from a missing omap (oid).
Mimic that behavior when using the api.

c14cbee132 journal: change omap set func to handle multiple key-value pairs
For any function that sets more than one key on a single oid setting
them as a batch will be more efficient.

0ac5f40d09 journal: change omap get func to handle multiple keys at once
Taking this appraoch means that any function that must get more than one
key's value from the same oid can be more efficient by calling out to
ceph only once.

To be cautious and avoid missing things we always request ceph return
more keys than we actually expect to be set on the oid. If there are
unexpected keys there, we will not miss the keys we want if we first hit
an unexpected key if we were to limit ourselves to iterating only over
the number of keys we're expecting to be on the object.

0b99bdaa82 journal: add omap.go with go-ceph based omap manipulation funcs
These new omap manipulation functions (get/set/remove) are roughly
equivalent to the previous command-line based approach but rely
on direct api calls to ceph.
